GRBL Module 13.2 Stepmotor Driver (SKU: M035) - Firmware upgrade

  • Hi
    Can anybody give me a hint, how to flash / load on the GRBL Module 13.2 Stepmotor Driver?

    • which hardware do I use to flash with Arduino IDE?
    • where do I find the firmware GRBL 0.8 for M5Stack module (i2c version)?
    • how do I have to flash it e.g. which board do I have to chose?

    Did anybody upgrade the module to GRBL V1.1?
    Can I just use the common Arduino Uno version?

    Thanks for your help.
