[@QuentinStephens]

I remember erasing EPROMs with UV light in the mid 80s and programming them over a serial link. Maybe they were as large as 4KB. Things have changed a lot.

[@noodle_Cx]

that sounds super jank lmao i'm glad things have changed xD

[@OpticalHaze]

I would use one of those for my old 90ies mainboard aswell. So I wonder if there is an adapter for the CH341a?

[@LayZeeDawg]

@@noodle_Cx me too, modding arcade game boards. I think I still have my UV eraser.

[@toninica]

Golden era. Electronics was not for everyone and not as much information as now. Beautiful times.

[@toninica]

@@LayZeeDawg I had one built from a mercury light bulb for street lighting.👍

[@insertintrohere]

The CH341a doesn't supply 5v to the data lines. So no need to mod it. If you multimeter it with no draw, it will show 4.7v, but once connected to the chip it will drop to 3.4v. Which is well within spec. Plus current is more important when you talk about burning chips.

[@MrJuanjo1997]

ikr, this guy has no fcking idea

[@micnolmadtube]

Do you know what the jumper pins are for? The yellow rows with one jumper located

[@matrix7479]

Always make sure to do at least 2 reads and compare using a program like HxD before you overwrite your chip. Neoprogrammer, and most other programmers, don't verify reads in any way so you can't rely on a single read. A bad connection that causes a bad read wont cause any errors and you will end up with an unusable backup.

[@Wingman4l7]

THIS! Extra reads are free, don't be tempted to short-cut good procedure and skip this step -- you may find yourself sorely regretting it!

[@escapetherace1943]

@@Pedro-ct8ou yeah you can't burn it out. Nobody has done it and the old model puts the correct voltage out on the read lines anyway. Now people have BRICKED their mobos but they do that with either reader and by pinning the programmer wrong, not making more than 1 read and not comparing reads and generally not knowing what they are doing, but yeah

[@cdhaag2000]

I'm pretty sure the included DIP socket is so you can solder the pins in straight.

[@krs2067]

voltage mod is not needed, 5v to the data lines are okay because it don't put more than 1mah in these lines, electronics repair school explained this

[@LeadFarmer813]

i did the silly SAM port clip on the air 820-3437 in 2017.. baked something and that was that.. i learned to take chip off on most boards excluding VGA cards as they usually work fine if not in PCIE slot. tip: 12:07 u can click detect on left side and should find it auto. and no it doesnt have pin detect, just same as prior ch341a no extra test circuit like RT809 orTL866II+ the black pcb tends to popcorn the layers very easy if u try to solder chip on it w very high temps.

Hello.. I would like to know more about your method please... I have a CH341A... Or if there is a page where they explain the steps to follow. Thank you

[@SiETechNotebookReparatur]

If someone knows how to 3d print and make a template, they can make a nice cover for it. And make the template free :) For the old one are several templates also accessible.

[@Adamant_IT]

If I had access to a 3D printer, I'd totally be into an enclosure for this that converted it into more of a "desktop" widget. The main reason I prefer my RT809f over the CH341a is because the RT809f is a box that connects with a cable, instead of needing a USB extension cable that's clamped to the desk. Plugging a CH341a directly into a tower PC is kinda clunky, although there's nothing wrong about it.

[@SiETechNotebookReparatur]

@@Adamant_IT Yes, the form factor and treatability are important when you use a tool on a daily basis. I have 5 programmers, ranging from cheap to quite expensive, but I still prefer to use the old EZP2010 simply because it is so compact, robustly built and handy.

[@Adamant_IT]

Is the software better for the EZP these days? I dropped my EZP2019 basically as soon as I got anything else because I found it super hit and miss with chip support and reliability. But that also might be because it was my first programmer and I was still figuring out how to use them properly.

[@vgamesx1]

@@Adamant_IT If you're interested, a monoprice select v2 can be had on sale around $99 or an ender 3 can be found for as low as $130 but takes at least an hour to build and without any experience another hour to get it configured properly, so not for the faint of heart who can't handle some troubleshooting, but otherwise both are great beginner printers.

[@SiETechNotebookReparatur]

@@Adamant_IT I never had any problems with the software (with 2010, I don't have 2019). It programs much faster than the CH341 and doesn't make any mistakes. When it comes to onboard programming, the CH341 recognises many EEproms, which is not recognised by EZP onboard, but when reading and writing, the CH341 almost always makes mistakes. So if EZP says it can't do it, but the CH341 does, it does it with error. My first one was the AJAWe 0812, but it was extremely slow. Then the EZP2010, SVOD1 (for EC), out of curiosity CH341, SVOD3.

[@m.l.9385]

In-Circuit programming worked very well for me. I was able to flash a Winbond BIOS IC in a WSON8 8mm x 6mm package with this program (v1.7 to be exact) last weekend. I restored the BIOS of my GPD Win Max 2.

The NeoProgrammer does not open Asus CAP files but there is a "CAP to BIN" program which can do that middle step...

Nice info about the programmer, you told me in earlier video you will get more into the bios programming . And tada here it goes. I subbed. We can exchange knowledge about this.

Looks like it's worth buying just for the adapter PCBs, of which one looks like it should support the USON (0.5mm pitch) footprint which is used a lot with Macbooks, especially the USB-C models for the thunderbolt ROM storage for each pair of CD32xx chips. Was going to design/fab my own but this would seem to be a simpler option ( and pick up some other interesting ones too I see ).

[@icommandoi145]

The volt mod is unnecessary and a lot of people get that wrong and blindly spread that misinformation and apply the mod without actually testing the Voltage on the pins directly. Even at 5V when you connect a BIOS and it requires 3.3V you'll find it reads 3.2 ~3.4 on the BIOS pins. No mod necessary.

[@JA-pk8jq]

I need help. I have tried over and over to reprogram the bios chip on a Surface Pro 4. It uses a winbond W25Q128FVPIQ. I tried attaching the ribbon to the chip on the board. I bought digital chips The Flash directly but they don't have that model ship anymore they don't make it they have a substitute it's the w25 q128 jvp IQ. I tried a Windows computer and I've tried Android I've tried as programmer and Neo along with others it's never automatically detecting the chip. And when it says it's writing it never works on the verification. I believe the issue at some point it has to do with the status registers. But I'm not sure I don't know what to do I need help please thank you

[@1marcelfilms]

I modded mine by cutting the 5v trace and put a solder bridge between the 5v and 3v pin on the back. no need for wires. also easily reversible if ever needed.

[@ModelLights]

First thought was wish I'd waited just a bit and got this one, since I just got the other type. Going to be much easier to accidentally leave that switch in the wrong position though vs use the 1.8V adapter, so second thought is OK I'm fine with having the other version. Make sure you keep checking the voltage every time on the socket with a voltmeter as part of your procedure, good practice and it's going to be very easy to forget and leave the switch in the wrong position if you get used to just plugging in chips without checking. Needs feedback. LEDs, red = 5V, yellow=3.3V, green=2.5V, blue=1.8V or similar would be good. Then you could just check the LEDs every time before inserting the chip and drop the manual voltmeter check.

[@Evhen_Velikiy]

Don't be paranoid. Even using the black CH341A board you don't need to do a volt-mod or volt select thingy or separate board for 1.8V chips. Yes, at idle you will see 5V on the data lines, but when you connect the appropriate chip, the voltage will automatically decrease to the required level. The fact is that the current in the circuits of the data lines of this programmer is so small that the resistance of the chip you are programming is enough for the voltage to drop to the required level. You can check this very easily by connecting the chip and taking measurements, moreover, this is how a lot of professional programmers work. I have been using this programmer for many years and not a single chip has been damaged by this programmer.

[@sipansibabdreddknot5179]

@@Evhen_Velikiy sorin also said this to the panic of 5v on data and power lines, checking upon it, it drops below the need voltage.

[@SmarkDepper]

I looked for the new version and it cost x5 times more than the dangerous non-modded one, also the clip accessories are missing. I think I'm fine with my modded programmer since all the chips I reprogram are the classic Winbonds. All the money I have now is going to electronic projects, somehow inspired by the previous mod.

[@AndrewInTO]

Been into tech since I was a kid, building PCs, etc. But very new to soldering, dealing with the more intricate side of electronics like this. Is a BIOS reprogrammer like this good for any kind of flash chip, with the right adapter, or is it meant primarily for the type of chips used for desktop and laptop BIOS? I'm thinking specifically of consoles, especially given the recent reports of Wii U failures due to a NAND chip going bad.

[@hardrivethrutown]

Great vid! I know I'm going to need to get one of these because I'm pretty certain I'll need to use one at some point. Also some kits come with a clip adapter on a ribbon cable used for SMD chips, I don't know if that's better than de-soldering and re-soldering, but it seems a little more convenient for my needs.

[@Adamant_IT]

I still hear wildly conflicting opinions about in-circuit flashing. I think there are plenty of times when it works / is safe, but also I think you need more knowledge about the device your fixing, specifically _what else is on the SPI bus_ that you will be sending power and signals to when you clip onto the BIOS chip. But yea, I'll be researching it at some point, as there are a few cases where it makes life significantly easier, and potentially more accessible for people who aren't ready to get into soldering.

[@vgamesx1]

Interesting revision but despite being affordable they still need to work on the price, it may have gone up a bit but either way, you can get the original for as little as $4-5, so even including everything such as a 1.8v converter, SOP to DIP socket and a clip, costs only about $10 shipped.

[@Adamant_IT]

That's a fair point. I feel like price is irrelevant once you're below $15, but certainly for people in poorer countries where absolute rock-bottom prices on tools make a big difference, the v1.6 is essentially twice the price.

[@vgamesx1]

@@Adamant_IT Well, I was thinking more so for beginners/hobbyist/someone starting out, for example I don't regularly fix computers, but I still wouldn't mind having one of these myself, however currently after shipping the new model costs $17 or more, actually triple what the old one costs, so yeah considering how little I would be using it, I'd rather spend the $5 and do the mod.

[@escapetherace1943]

ali express has tons of them. However you don't need the updated chip. The 5 volts was never an issue and if you are connecting the pins correctly on the original chip you will get a 3.3v out. Flashing a 3.3v bios chip with 5v isn't going to damage or burn your chip out anyway, it just might make reads/writes a tad more unstable. Can you even find evidence of people burning their chips out with the original? lol. no. You can't. plenty of people brick their mobos but it doesn't matter which chip they are using, they skip steps and pin it wrong. The original chip is completely safe/fine and if you're ultra paranoid you can solder 2 little connections on it to make it only run 3.3v. For me, it worked

[@Levy_Wilson]

@@escapetherace1943 You say that, but I went ahead and just bought the v1.5 kit with a 1.7 adapter. One of the chips I needed to flash was a 1.8v chip anyway, so having the extra voltage selector was best.

Question: Did you figure out why they added a IR remote control receiver in the new version?

[@Adamant_IT]

Apparently it's for decoding TV remotes and such like, which makes sense, as I can't think of anything else still using IR for communications.

[@ModelLights]

Reasoning is easy enough, it's a quarter or 50 cent part that lets you check remotes and maybe even back up the remote codes etc on a piece of test gear you're already going to have around, instead of having to have or find something else to do it. Near free extra function. The real question is what pin is it on, and if the rest of the programmer is basically the the same the software should work and we can add it on the other versions. You can check if a remote works at all easily, just point it at a cam most pick up infrared. But if this will read the codes and store custom codes it'll be handy vs having something else around to do it. Don't need it often, but it's not a bad cheap add on since it's already a USB attached test device..

[@ModelLights]

Actually there's more. Looking around the site for the main files later, this came up : CH340IR.ZIP CH340 USB to IrDA infrared WINDOWS driver, support 2000, XP, for USB infrared adapter based on CH340, USB to infrared interface. And a CH340IR.E**, changed of course.. USB to IrDA infrared WINDOWS driver for CH340, used for USB to infrared IrDA interface, USB infrared adapter, used to distribute to end users with the product. Whenever I run back into my IRDA parts I'll tack one on and try and get it running. Low priority so may be a while but I should run into them eventually.

I don't think you can really add a volt select to the older one. I missed it in the video, but the voltage conversion is done by a dedicated chip under the socket - which is why the socket is mounted wonky. The PCB needed to be completely redesigned for this. However, if you've done the 3v mod to the original CH341a, and you own a 1.8v converter, you basically don't need this updated version. Although it does 5v and 2.5v as well, I've never seen chips of those ratings.

There is no amperage on the lines that idiots are measuring and thinking they need to mod the device. You can't program with voltage alone, you need amperage as well... yes, some of the pins may read 4.xV, but at 0.02A, it's not harming anything (mainly because those high voltages only show up when there's zero load, and drop to near zero once a chip is socketed)

I have to clear cmos on every boot computer works fine after cmos clear but if I dont clear it it does not boot I have good power its a older motherboard 2011 asus the button cell batter was dead replaced it flashed new bios but nothing change do you think its a bad chip I have unpluged drives changed out everything was working fine just all of a sudden have to clear cmos every boot thanks for any help I love your channel

How can I know if the base Version can damage my bios chip?

[@peteralexander478]

Has the problem of AliExpress not being able to send some items to UK addresses troubled you much?

[@arieettinger8175]

can you use this programmer to read the 93cxx series eeproms?

[@casey6192]

Where to get drivers & software?

[@tulsatrash]

Having now used this. I do wish you could alter the speed it runs at. The faster and SPI programmer goes the shorter the data cable you need. I had to shorten the tail on my flash clip by more than half in order to start getting reliable reads and writes. That said it's small convenient does the job, doesn't care if you stick it on the end of a long USB extension cable, as a built-in voltage switch, and a diagram to remind you which way things are supposed to be put into the ZIF socket. I really like it. Thank you for telling me this device exists.

[@NathanCroucher]

Still happy with it, any recommendations? I seen this new one, it looks pretty good but no software yet, "CH347 Development Board".

[@Martin-ot7xj]

Hi there , it was perfect . thnx

[@kztech1319]

Hmm interesting. I think it would be nicer if it came with a SOP8 socket that you can plug the chip in and directly into the programmer... Theres also the clip but that can be wonky at times when sometimes the circuitry on the motherboard just doesnt play ball. Also on some Dell and hp laptops, if the bios chip is missing, the power rails might start for only a few seconds after plugging in charger and then shut off, and won't even try to POST without the bios chip.

Question: please what is the name of this programmer..have tried checking it out on ali express forum..can't find it

[@DanielsGameVault]

I DEFINITELY want to address the elephant in the room: what's the IR remote sensor next to the socket for ??? :O :)))

[@DumahBrazorf]

The board can work as a programmer or a monitor. I suppose you can read infrared comunications, like remotes, so you can then clone commands on your projects.

[@Wingman4l7]

Any particular reason why you desolder the chip instead of reading it using a test clip?

[@Adamant_IT]

Clips are fiddly and intermittent. If you get one that works well, they can be great, but getting a good one seems to be somewhat luck of the draw, and even then it won't help you for WSON chips. Then there's the other issues of flashing in-circuit, where the programmer will be powering up and communicating on the whole EFI SPI bus, which includes lines going to delicate places like the PCH. If you know the platform well, this is fine, but I've seen weird stuff happen. IMHO, desoldering the chip is safer and more controlled, and if you're doing this level of repair work, it's really not a big deal to just take the chip off the board.

[@Wingman4l7]

@@Adamant_ITGood point on the surface mount chips! Every single clip I've seen (and all the ones that come with the CH341a) are junk. The one that seems to be regularly recommended is the Pomona 5250, which costs as much as the whole CH341 ($18-20 USD). You can buy a cable that plugs into the SPI diagnostic / programming port, instead of interfacing with the chip directly, but the cheapest you can get a set (there are 3 different connectors over the Mac model years -- MOLEX 30pin, HIROSE 30pin, HIROSE 12pin) is ~$50-70 USD. Nice to use though on the Macbook Air -- you don't have to remove the motherboard anymore to flash the chip since the port is on the top of the board.

Thanks for the educative videos. Please I need your assistance. I am trying to program my dell precision 3530 bios with Ch314a and neopprogrammer. My bios chip is labeled W25Q80DVSIG but the list of detected ic in neopprogrammer are: 1. W25Q80BL 2. W25Q80BV 3. W25Q80JV Could you please help me identify the right one from the list
