Some are under $10 and should be enough for I2C and other slow speed protocols (<10MHz).
Ahh ok thanks i will order one so i can test the I2C.

Re: Esp32-s3 Custom PCB. I2C not working.

Can you use a scope or LA to look at the signals on the I2C pins? Hi, Thanks for your reply. I don't actually have one. Do you know of any cheap ones I can get just for this use? Would a picoscope work? "https://www.picotech.com/oscilloscope/2000/picoscope-2000-overview" as i have used these in col...

Esp32-s3 Custom PCB. I2C not working.

Hi Guys, I have been working on my own custom esp32-s3 epaper watch. I have manged to get it all working know apart from the I2C bus. I'm not sure why it is not working. I am using Arduino ide to program with the ESP32-s3 Dev board. I have tried to initiate all the sensors using normal wire and twow...

Re: A fatal error occurred: Packet content transfer stopped (received 8 bytes) on EPS32-S3 PCB.

Hm, not sure then... possibly you can run esptool manually with the --trace option to show where it goes wrong? Also just noticed if you look in screenshot below the SPIQ and SPID lines are the wrong way around when compared to this section in the esp32-s3 datasheet as seen in other pick below, whi...

Someone just mentioned to me in a discord that the flash mode that I am using is incorrect because they sent me this link "https://docs.espressif.com/projects/esptool/en/latest/esp32s3/es...

Re: A fatal error occurred: Packet content transfer stopped (received 8 bytes) on EPS32-S3 PCB.

Does this also happen if you force the ESP32S3 into download mode, e.g. by holding BTN2 on powerup of the watch? If i dont force the esp32-s3 into download mode it will just keep disconnecting from the computer and reconnecting. But once i do force the esp32-s3 into download mode it then stays conn...
