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. You can also select clock speeds, upload speeds and generic boards with external cystal.
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!
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
Each time a PR is merged, the release action will be triggered.
The following steps are executed
- Generate the release artefacts (the lgt8f-1.0.x.zip file)
- Update the
package_lgt8fx_index.jsonfile with the new version - Commit and push those changes to the repository
- Generate a release with the artefact.
PRs that only touch the readme.md file, or the /docs folder will NOT trigger a release.
The action can be found here: https://github.com/dbuezas/lgt8fx/blob/master/.github/workflows/release.yml
