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!!!

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).

@@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.

@@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.

​ @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.

@@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.

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.

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

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!

I would buy 5 just for that slick black coloring.
