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
- paste this url in Boards Manager URL:
- Go to Tools/Board/Boards manager
- Type
lgt8fxin the search box - install lgt8fx
- Type
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

- And you may also find something in the closed Issues
- Core is based on Larduino_HSP v3.6c with fastIO backported from https://github.com/LGTMCU/Larduino_HSP
- And inspired from Ralph Bacon's video: https://youtu.be/Myfeqrl3QP0 (Check his channel, he's uploaded a lot of great videos)

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