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.
- Fast_IO update
- Automatic prescaler setup
- In Menu support of 1, 2, 4, 8, 16 and 32 Mhz
- Digital Analog Converter
- Voltage References INTERNAL1V024/INTERNAL2V048/INTERNAL4V096/DEFAULT/EXTERNAL (useful for example for analogRead or DAC analogWrite via analogReference(xxx));
- Analog Comparator (page 224 of datasheet v1.0.4)
- Differential Amplifier. See this Example.
- Computation Accelerator (page 52 of datasheet v1.0.4) Work by others

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
