How to install

Add the package to the arduino Boards Manager Urls:

  • Go to Preferences
    • paste this url in Boards Manager URL: https://raw.githubusercontent.com/dbuezas/lgt8fx/master/package_lgt8fx_index.json
  • Go to Tools/Board/Boards manager
    • Type lgt8fx in the search box
    • install lgt8fx

Now the boards appear in the IDE and you can also select the clock speed.

32Mhz is twice as fast as a conventional arduino nano! Actually even faster as many operations take less clock cycles than in the atmega328p. Check out some benchmarks

PS: Just want to say thanks for this git, helped me a lot!

Disclamer

I have no association with Arduino, Logic Green, Atmel or anything. I just wanted to have a convenient way to use these boards and get them to work without hacks at max speed
