Thank you for the reply and the tips. I undestand that it is hard, but we are doing it because we need the extra gpio that the chip provides and also the cost sensetivity of the product. Could you provide some help on how to measure the impedance or the rf performance without any specialised tools? ...

Goes everyone is struggeling with this one.

Hi, I have developed a custom PCB usingn the esp32 s3. I have a reference devboard with the same chip, that i tried to copy the antenna design from. Unfortunatly my antenna doesnt seem to work, since i cant detect a wifi signal.On the reference board (LilyGo-T-RGB), the same code works fine and i ge...

OK, I tried my board out and out of the box, the USB worked. The only issue was that when i first pluged it it, the com port kept disapearing ON and OFF every second on windows. After i held the GPIO0 button down and power cycled the board, the com port is recognised fine and i could upload my code ...

Hello, I am trying to make a custom pcb to drive an LCD using an ESP32 S3R8 chip. I read that you can program it directly using USB,which is what i am trying to use instead of UART. My question is, does this work on a brand new chip or do i need to flash something to it using uart first? I am attach...
