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?

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

Thanks for your help.
