Is this the most functional ESP32-S3 dev board EVER?

[@UnexpectedMaker]

Great job on the board! So, RSSI is not useful in testing your board's RF match/performance as it's really an indication of how good the TX is on the networks you are scanning, not on your own. You'll only know if you RF match is ok when you measure your own TX performance. For instance, a really bad match could still see other networks, but not be able to TX at all due to reflection. Keep up the great work!!!

[@hxtec32]

OH MY GOSH! Unexpected Maker himself. Thanks so much for your comment bro! I still have a lot to work on with this board, including making it breadboard compatible, and I really appreciate your open source schematics, as they have helped me greatly understand how to make ESP32 boards. You literally inspired me to make these, and it’s so so cool to see you commenting on my video. So, how would you measure TX performance? As you could probably guess, (and I have stated in the video), the second CLC is just a 0 ohm jumper at the moment, so I didn’t expect it to perform well. And, I only have other S3P boards, not even an oscilloscope or VNA yet, so do you have any suggestions? Thanks so much bro, I’ll definitely make a better version of this board in the future. The 35 + j0 ohms is matched to 50 with the first CLC though, so it might not be too bad (I doubt it’s great). Would love to collab some time, I also live in Australia, and I really like your designs (the TinyWatch is pretty cool).

[@UnexpectedMaker]

@@hxtec32 The antenna you chose needs to be tuned to 50 Ohm on your board - without tuning, it's not 50 Ohms. This independent of the CLC to convert the 35j0 to 50j0. Check the datasheet for some default matching values to match the antenna itself to 50 Ohms, but they really don't translate onto a custom board, but might be better than no match at all - hard to know without measuring it :( They also require a T, not a PI, and unfortunately, the only way to measure, tune and test your TX is with a VNA :( Where is Australia are you? If you are in Melbourne, you can come over and I'll show you how to tune your RF on my VNA.

[@hxtec32]

@@UnexpectedMaker that would be so great! Thanks so much, if we come down that way, I would love to learn how to tune my board! So, does the matching circuit for the antenna vary at all? Is it always a ‘T’ network, or can it be other types? Because, in the data sheet of the antenna I’m using (Johanson 2450AT18D0100), it has a pi network as an example, but I’m unsure whether this is to match the antenna to 50 ohms, or match the output from the MCU. Thanks again, would love to learn from you since there isn’t that many tutorials on using chip antennas online. I might get a LiteVNA soon, but I haven’t exactly had a need to use good performing RF in any of my projects yet, but it would still help. Btw, I noticed while testing the ESP-NOW, BLE protocols (TX), the chip started to get pretty hot (the bottom of the PCB felt like ~50 degrees or so. Is this normal, or a bad sign of the antenna wasting too much power? Thanks for your advice man, really appreciate it.

[@UnexpectedMaker]

​ @hxtec32 Oh, that’s the D100 and not the B100, ok, so in that case, without a VNA you can’t really work out the match topology needed, but likely would only need 2 components, so a CLC could also work as a T. The chip getting hot is because the TX is not matched right, and it's reflecting the TX power back into the ESP32 which could damage it - so I'd stop using it with the radio until you sort out better matching. That's the thing with RF - it's easy to put nothing or a bad match down, but most people don't realise the implications of doing that.

[@hxtec32]

@@UnexpectedMakerdang. Thanks so much for that info, didn’t know that’s what was happening. I knew it had something to do with poor matching though. I have done some research into smith charts and I remember finding a really good video on tuning antennas, so I’ll have to try my luck at that sometime. I would definitely be keen on you teaching me how to tune an antenna though, if I’m down at your location. Thanks for your helpful advice, mate.

This is probably covered elsewhere but having real practical examples and a real life walkthrough is invaluable.

[@hxtec32]

Well, from KiCad, simply just export the gerber files, as according to their webpage (search up exporting gerber and drill files in KiCad 7 PCBWay), and the BOM needs to be modified to their requirements, however the component placement doesn’t need to be. I may upload a video on Google drive for you explaining, and consider making a video later. What CAD are you using?

[@beniseman2952]

Great work! Really impressive for a 13 year old. Excited to see what you will make next. At the start of your video you state a goal of breaking out all available GPIOs but this seems to have changed during your design process but you don't address it. Setting a clear expectation means you'll be judged against it. Breaking out 21 pins is well short of *all*, and is actually the same as the UM FeatherS3 which you used as an example. Some suggestions for future iterations: - Get rid of duplicates in the headers. 2 pins each for reset, boot, and LDO2 is uneccesary. 4 VIN and 5 ground pins is excessive. Thats 8-10 spots in the headers that can be used for something else: you can break out more pins, just use smaller headers and make the board smaller, or use that space for another circuit. - Label your headers - Add battery charging IC. A basic ic like the tp4056 and the associated fet, resistors, and caps comes to ~15¢ and makes the board portable without the need for a battery hat (XIAOS3>Adafruit QTPY on this alone, just wish XIAO had a chip antenna version) - breakout LDO1. at 1A there's plenty of headroom on top of the S3 and people are going to want to power some peripherals off of the main LDO so they can cause wakeup from deep sleep. - LDO2 should not enabled by default. have this enabled by VDDSPI, a GPIO, or both using and AND gate as UM has done on his boards. any peripheral that isn't going to serve as a wakeup trigger shouldn't be powered during deep sleep. having a microSD attached, anything on I2C with pull-ups is going to take you from uA to mA in deep sleep. - add a second user button or place boot further away from the reset button so you don't have to worry about accidentally triggering it. - consider adding I2C connector or pads so that one can be soldered on. Again, congrats. The moment where you plug it in and react with pure joy was wonderful. Anyone who has made a custom PCB knows how that moment can go either way.

[@hxtec32]

Hey mate, thanks so much for your comment and advice. While it would be great to break out more GPIOs, I was unsure at the time whether I could use the JTAG pins as IOs or not, which I have verified that I can use them now (I think, haven’t actually tested though, just research.) Also, I said ‘all usable’ so this doesn’t include IO3, 33-37 (used for Octal PSRAM), the UART pins, and many more that are less than optimal to use. Like, I could have configured the UART pins to be GPIOs, and I could use IO3, but what’s the purpose? Getting a few extra IOs in exchange for potential issues with your board was not worth it for me. I do 100% agree with your statement of the pins being doubled not being great, but I honestly didn’t know what else to do with the extra pins of the headers. This is my first time making an ESP32 board, so yeah, I did do a couple oopsies 😅 Yes, I2C pads or headers would also be great, but would only require some 10k pull-ups which I could easily add. Something I forgot to mention in this video, is that this is actually an application specific board, for my line following robot, and I didn’t have anything that needed I2C, hence why I went with this configuration. This also follows up to why LDO2 is always enabled: I will be frequently using the buzzer for my line following program, and it draws 200mA, so I tried to spread out the load more. Deep sleep was also not a concern for me, I am not using this board for that, just high performance, sensor readings, etc. I don’t actually know how to use that as well. You say that I should add a battery charger, but that is the very reason why I created this board, actually. The TP4056 is for 1S, and I’ll be powering this board with 2S and 3S, and obviously, charging circuitry for this takes up much more space. That is why, the voltage regulators theoretically allow up to 18V, and I need to use multi cell LiPos because I am powering DC motors for the line follower. Of course, regulating 7.4 - 12.6V down to 3v3, 1A, is much more space efficient than regulating 3.7 - 4.2V up to 9V, 4A. As for the buttons, I’ve actually found them much easier to use, as I can enter download with my thumb by rolling it across the two, making it pretty convenient. Yes, they could be moved further apart though. And, the boot button (IO0) can be used as a GPIO after boot, so it functions as a user button when running programs. One of the main purposes of this board was to make it very small, so that is why you don’t see some of these cool features you list here. The headers are not labeled, because I actually couldn’t fit all the text, and there’s probably only gonna be 2 people out there using this: me, and the guy who won the giveaway. Anyways, thanks for your feedback, and I’ll definitely consider these features for a future board.

[@beniseman2952]

Ahhh, all of my suggestions are in the context this being a dev board with all pins broken out, not something that is project specific. Can't use 33-37 with Octal but you can use the strapping pins without causing problems provided you respect the boot state implications. I'd burn some eFuses personally. UART can be used. Most projects aren't going to come close to maxing out, but I've done it and it caused me to toy around with making an as small as possible dev board with 1.27 headers or B2B connectors to have everything broken out for prototyping and be small enough to use in a finished project while remaining modular. Salvatore Raccardi's OBJEXLink is a great example of this, just with fewer pins broken out. But tiny! kzbin.info/www/bejne/jmOcfayOYpaisKM Again, great job. Impressive and ambitious for a first board. Keep it up!

[@ressamendy]

From what I see, it's been a while since we crossed 500 subscribers. It was a very nice video. You also expressed the issue that makes me particularly angry. Why would we want to give up many features when something becomes mini? Anyway, what I want is to add an sx1262 lora chip to this structure. Let's see if it will be the way I want it to be. And I have a question for you. When I examine the dev boards, they do not support both Arduino IDE, ESP IDF and Microphyton infrastructure. I think having so many programming infrastructure options will greatly increase the popularity of these boards. Especially if you consider the difference between the ESP version supported by the Arduino IDE and the version of the ESP IDF, you can understand what I mean more easily.

Thanks bro. Yeah, I’m not sure how ESP-IDF works but I know micropython should work with this bc it’s USB flashing, I’m pretty sure you just have to put a boot loader on it. I have already done the giveaway, if you check my community tab, you’ll see the guy who won, and the board has already arrived to him.

Inspiring work. Well made video too. Thanks for sharing!

This looks a very similar form factor to the WeAct S3 mini board albeit you have more flash and ram but most people don’t need anywhere near that much. Edit: the WeAct board has 35 GPIO although only claims 27 so some might have other uses and it appears to have a neopixel too.
