For the Raspberry Pi (RPi) low-cost educational computer, the Raspy Juice Expansion Board is a compact piggyback PCB board that power supply the required and regulated +5V to the RPi from a wide range of voltage sources, provides an RS232-level console breakout port and a real-time clock. The secondary feature of Raspy Juice is its expansion ATmega168A microcontroller that has interfaces of an RS485 port, an additional RS232 port, 4x RC servo ports, and an expansion pins header for the MCU. This microcontroller and its interfaces are for simple robotics and other interfacing experiments.
