@felmue said in Stamp Pico USB Serial: Or in other words, there is no way to directly connect D- and D+ from the USB-C breakout to the M5PicoStamp. Hi Felix, thanks alot for that information. Was hoping this converter could be easy be done by some ICs and restistors maybe but would be too difficult for me yet. So i think i will get another controller with built in or a cojntroller with onboard USBC connection. Makes no sense to spend much time and money if the device will be procudes 100 times each with MCU and a serial converter. Your help was great!!! Best regards Hannes

@m5stack How can I get bin file from the device?

Hi Just add HardwareSerial Serial2(2); under #include <Arduino.h> in /Users/matthias/Documents/Arduino/libraries/M5Stack/src/LoRaWan.h

So, I have 2 m5stack core with me. My idea is to have these 2(or potentially more) to communicate with each other via LoRa, one to be a sensor node, and another acts as a receiver. The receiving node will then upload the data received from the sensing node to thingspeak. The components used in this system is the ENV sensor, and the LoRa modules. I hope this explains what I am trying to do.

most M5Stack Arduino API , you can find it from this page. link:https://docs.m5stack.com/#/en/arduino/arduino_api
