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

PCBWay is one of the most experienced PCB manufacturers in China, consider them your one-stop solution that offers PCB fabrication, turn-key PCB Assembly, PCB design, 3D printing, and CNC machining services.

The S3P is a small development board that I created which is just 34x32mm and includes as many features as I could pack into it. This includes:
a buzzer
a neopixel 1515 LED
21 GPIOs broken out through double-row headers
second 3.3V user LDO up to 1A
up to 16V input voltage to linear regulators
ESD protection on USB-C port, and battery voltage pin
16MB flash, 8MB PSRAM
Chip antenna (not fully tuned but still performs pretty well)
and, a whole bunch of other stuff that I probably forgot to mention because there's so much.

If you'd like any advice for designing your own ESP32-S3, I'd be happy to help if you commented down below, because I definitely get how it can be really hard starting out with these types of boards. They probably don't teach you this sort of stuff in school, and, personally, I had to learn every aspect of this board myself through YouTube videos online and datasheets. The chip antenna was one of the hardest parts of this, since there isn't much information about using one, just PCB antennas, and, to give you an example of where I was when I started this board, I didn't even know what a transistor did, and how I could use one. So, while this is a more 'testing and building' aimed video, and not as much a tutorial/educational video, I can still provide you guys some personal help if you want it, just leave a comment and I'll reply soon enough.

Don't worry, you will see more content with this board; I know this wasn't a great full demonstration, but I don't even have an oscilloscope or spectrum analyser yet, nor can I afford one, so there's not much else I could do with it for now. I will be using this board in a custom line follower though, which you'll be seeing in one of the next episodes.

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!!!

It always makes me happy to see the internet doing what it was supposed to do back when it was created. Making information accessible to everyone. It is so amazing to see an autodidactic like yourself being able to accomplish so much, at such an early age. 40 years ago when I was your age, it was so difficult to gather information on new or evolving technology. Keep up the great work! Thank you for sharing.

Dude, you are already at 2k and we are going to be here for the 1 mil 🎉amazing job.

[ParshvaPatel-iblm]

You are awesome man at the age of 13 you can achieve this is insane keep going

[sorryboss]

Good editing skills, perfect script planning I mean ignoring the fact that you’re engineering and giving tips at a young age, those two are impressive skills.

“Reading data sheets, and studying schematics until one in the morning”. SUBSCRIBED! 👍🏼😎👍🏼

[nebiru]

great video production and the board is sick!

[voxnihl]

I would buy 5 just for that slick black coloring.

[taralalram]

You're the kid I always wanted to be. I'm 54 and still working in IT but it's never been as satisfying as watching your channel.

[TheDigiSync]

Just wanted to say I'm impressed! I'm an embedded engineer (+20 years) and found your video while looking for info on the ESP32. I found your video to not only contain the best knowledge compared to others, but I also found it to be better in regards to video editing and flow. I'm now a subscriber. Keep up the great work young man!

[codyorlovsky]

Great work buddy. When I was 13 I was interested in this stuff but I was definitely not at the level you are now. I am now a computer engineer for a tech company I helped start, designing boards and wiring FW/SW. Keep it up!!

[raakobihai]

This is a really good project! I would totally watch a full length video of you walking through the design process!

[EveryFlavorRobot]

DUDE! WHAT this is awesome! Your board is a great idea, and well-implemented as well -> I'm impressed and inspired.

Definitely going to try to make my own S3 implementation to integrate into some of our projects after seeing how well this worked out. Keep it up!

[skylermansfield]

This is amazing, the boards from PCBway look so good and I can't believe you got it all working so well first try, nice job! almost every first pcb round I've done needed bodge wires on it oops

[SurohStreams]

Very well done! I'm impressed by your work and how much you got out of that ESP32! I still have some very small Boards lying around with only 2 GPIOs, so seeing the potential for the chip is eye opening!

[larrybowers]

Great job on both the quality of the video and the great Dev Board. It's nice to see so many capabilities in such a small package. With 8M of PSRAM, this would be perfect for driving TFT displays and would be cool to see a companion board that this could plug into to quickly connect a display.

[Technikfreak]

really Next Generation ESP32 Dev Board! Great work! You should make a Kickstarter campain.

[PastThePoint]

New sub here. Impressive work, bud! Can't wait to see what else you come up with!!

[Spacewarpstudio]

Amazing stuff, you are extremely talented! I find it remarkable you have learned all of this already at such a young age.

[JaaoPonte]

Your board is impressive, very nice design!
