Review on πŸ’‘ Enhanced Adafruit Trinket M0: A Versatile Hardware for CircuitPython & Arduino IDE by Jon Bishop

Revainrating 5 out of 5

The best gimmick. suitable for computer components

I've used these tiny things on several projects. I log into TRINKETBOOT and flash the firmware using the Arduino IDE. Remember you can use UART and I2C together or SPI separately. If you use SPI you lose UART and I2C. And remember, if you're using UART for serial communication, it's actually Serial1 in your code. for example. Serial1.print("Example"); It is not shared with USB. The Dotstar LED is internally connected to the digital pins D7 - data, D8 - clk

Pros
  • Very good price
Cons
  • The list will be long.
