      Question

      Does anyone know if it is possible to upload from Arduino IDE to the Stamp-C3 using the PORT.U pins (GND, G18/D-, G19/D+, 5V) instead of using the USB-C connector? Since the ESP32-C3 does not support OTG, I assume that PORT.U and USB-C are the same, no? Otherwise, using the ESP32 Downloader Kit via the ISP pins would be the only solution if one wants to go through PCB, right? Thanks!

        Hello @davekc

        M5Stamp-C3: PORT-U pins and USB-C are not the same. Check schematics here.

          Hello @felmue,

          To be honest, I doubted your response, and I had to review those schematics to realize that I had missed it. Thank you so much!

          Regards,
          Dave
