IchigoJanai (in preparation)

Open-source hardware board implementation for IchigoJamⓇ. There is no relation between IchigoJanai and IchigoJamⓇ, and no need license fee for using IchigoJanai.

8Mduino UNO R3 (in preparation)

This project allows the microcontroller (ATmega328P) used in the Arduino UNO R3 to be used with minimum external components. This development board is low cost as it does not have a power supply circuit or interface circuit, and the microcontroller runs on the internal clock (8MHz), eliminating the need for an oscillator.
