Cool! One tip, already noted, is to use buck instead of LDO if voltage drop is "big". There are many simple alternativet, just remember - use a short switching loop 😊

[@MMuraseofSandvich]

Re: Perfboard compatibility, I totally feel ya. Sometimes you have to calculate the position of each pad in the footprint rather than rely on the grid or the measuring tool. Luckily KiCad's fields all take mathematical expressions.

[@sycko2516]

Awesome, I really like the design!

This kid is going places

[@hxtec32]

Thanks bro, appreciate the support

[@UnexpectedMaker]

Well presented :) I'm looking forward to seeing your line follower robot build!

[@hxtec32]

Thanks so much mate! I appreciate it, I’m still trying to tune the line following program so that it’s fast enough for the video. 8 line sensors will probably do it though, thanks

[@user-go6kw3ye3u]

Man you are good, keep it up

[@quicksketch7]

Awesome video, thanks for sharing your learning journey! For a newbie in PCB design this is incredibly valuable. Much appreciation!

[@hxtec32]

Thanks dude, so glad that my video was serving it’s purpose to try to teach people 😁

[@santynolo]

very cool, the LDO overheating problem is very common in linear regulators, since Power dissipated=(Vin - Vout) * Amps. if you input 12v, and your board uses for example 500mA, you would get 4.35W dissipated in 2x2mm, which is not good. It's going to be definitely harder to implement another type of regulator, like a buck converter, but it's going to be better if it decides to overheat and desolder when using more than it can handle. For now, i think it's ok if you dont use wifi constantly, like a server or somethin. I almost burned myself one time touching a linear regulator connected to a 9v battery and an esp8266 board😅

[@hxtec32]

Oof. That’s not good. Yeah, I honestly should have used a Buck converter, but I felt like I didn’t have enough space even though I could have expanded the board by just a little bit. Thank you bro!

Great! Waiting now for the WiFi test results like the RSSI.

It’s in the testing video mate, go to the end, and it’s in the end screen. It’s also in the description if you want to check it out, would appreciate it 😁

[@mohamedrafeeq565]

Hi video look cool and well explained could make detail video on RF designing

[@hxtec32]

yes, in the future I am planning to

[@SinanAkkoyun]

What matching res/caps did you settle for for the antenna? Does it also decently work with 0Ohms and NC?

[@hxtec32]

haven't tuned it. 0 ohms and NC works horribly, haven't done any RF testing since this video. I also don't have a VNA to even perform these measurements :(

[@ariasairforce]

Hey, how did you figure out KiCad and electronics stuff? Like, what did you use to learn and get good at it?

[@adamarzo559]

Excellent video, very informative and well presented. Can you share the document shown at 7:30, and why vias under the chip is a bad practice? Vias under components in the rf section would be bad practice but i see a lot of vias under components like microcontroller, i thought it was okay. Learning a lot with your videos, thank you.

[@hxtec32]

Hello sir! Thanks, the document at 7:30 is the ESP32-S3 hardware design guidelines, Schematic, RF section (you can search online since KZbin has blocked links in comments). I think you might be right actually, grounding vias for the flash chip might not be bad, but I imagine that, because it isn’t connected to the top ground plane, there could be worse thermal performance. Idk if that’s an issue tho, thanks!

[@adamarzo559]

@@hxtec32 Thank you! I am still new and learning so probably way above my head so I am also not sure but no doubt in this case it would be fine.

[@hxtec32]

@@adamarzo559 thank you bro

[@spambot7110]

Kicad 7 has trace rounding (i think 6 did as well?), and i've never had problems with stitching vias in Kicad 6 or 7. are you sure you're not accidentally using an old version?

[@hxtec32]

I’m definitely using KiCad 7 bro.. yeah idk what happened there, but for me, I needed a plug-in to be installed. Maybe I just didn’t find it, but it was already there before the plug-in 🤔 Anyways, thanks for your comment

[@spambot7110]

@@hxtec32 oh, looking at the thumbnail it sure does say 7! i think you said 6 at some point in the video and that threw me off

[@sammybrown6730]

Which board did you slelect in the boards manager of arduino or platformio? Did you have to do something extra as it was not a dev board? Thanks!

[@hxtec32]

UM ProS3, because it has the same USB programming, and 16MB flash, 8MB of PSRAM

[@sammybrown6730]

​@hxtec32 thanks! I recently started making my own pcbs and just like you, I want to go smaller yet functional. Great video! Keep it up!!

Do you want to share you Kicad files? (schematic and pcb layout). I willl like to study you layout before I start my own hardware design

[@hxtec32]

Hey bro, I have the schematic on the GitHub, but I won’t be giving the pcb layout unfortunately, as I am going to sell a similar product soon. This video, is as much information as I’m willing to give for free, and the schematic + coding of course. Just check the description for my GitHub

[@aaryavtech]

Hey! Could you share me your Bill of Material & Positions file seems like my KiCAD is bugging out

cool

Where did you learn c++ for Arduino programming Day 3 of asking lol

[@hxtec32]

Hey bro, sorry i havent responded quickly. I learned a lot of c++ from dronebot workshop, i also looked at a few esp32 examples online from random nerd tutorials.

[@vachantheepic2825]

its ok i understand, thank you for the quick reply anyway@@hxtec32

[@vachantheepic2825]

also btw in the pid line follower robot when one of the motors weren't turning and you said it was because of low output of pwma, you said you changed the code but i couldn't see any difference in the code (from the perspective of the video) can you please tell me what you changed? ty@@hxtec32
