      Is there a way to access a second hardware UART on the M5Stamp-PICO?
      I do not need the SPI port but I do need the UART (and I2C) and uploading code while also using the UART in the application is really inconvenient.
      Any help appreciated.

        Hello @didier9

        for UART you should be able to use any available GPIO for RX and TX like this:

        Serial2.begin(115200, SERIAL_8N1, <RX>, <TX>);
        

        for I2C you should be able to use any available GPIO for SDA and SCL like this:

        Wire.begin(<SDA>, <SCL>);
        

        Thanks

          Hi Felix,
          Sorry for the delay... my STAMP_PICO project was momentarily shelved but I just resurrected it and found your response.
          I will definitely try your suggestion since I would like to keep the native port to flash but I need another UART.
          Thank you!
