The 644/1284 User’s Manual has just been published, and is now available for anyone to use. The manual includes information on the board specifications, installing drivers, IDE configuration, programming examples, and more. Also, why I prefer 8 bit MCUs like the Microchip ATmega, over 32 bit options.

I decided to propose this board with a Microchip ATmega644 or ATmega1284 8 bits MCU because I find that these parts are perfect for Arduino development. As compared to any other MCU technology available, even in 2020, the Microchip 8 bit ATmega option is by far the easiest that will allow you to create a large program on a very compact board. The 8 bit architecture is very efficient and reliable. Some others MCU and particularly 32 bits MCUs offer much more raw power, but ATmega644 and ATmega1284 MCUs are still a very good option if:
