Archiduino is a platform open-source (and open-hardware) with a modular programmable controller, 100% software compatible with Arduino Leonardo.

They are a real-time clock, an external EEPROM, an SD card (optional) and the predisposition for connection with our LCD board that also implements 4 keys. (more…)
