Raspy Juice is an experimentor's expansion board to power supply a Raspberry Pi 
(RPi)
host computer with a regulated +5V from a wide-range voltage source. Main features:
-
a 6 ~ 23V to +5V, 3A high-efficiency DC-DC SMPS buck regulator, with the ability to be powered from a variety of external sources such as batteries, 12V power adapters, solar battery sources, etc.
-
an RTC real-time clock
-
an RS232 level translator to breakout the host console serial port from the GPIO UART
-
an expansion AVR ATmega168A microcontroller (MCU).
The expansion MCU interfaced to the host computer as an I2C slave device, provides the services of controlling 4 channels of RC servo outputs, an RS485 interface, and a half-duplex software-based RS232 interface. Additionally, the spare pins of the MCU are brought to an expansion header which may be used for other purposes. The MCU firmware is upgradeable by the host computer and may be reprogrammed for other application-specific purposes. More details can be found at http://code.google.com/p/raspy-juice/.
This Beta Board early release is intended for developers interested in enhancing the MCU firmware, or for those just interested in powering the Pi from batteries, other voltage DC adapters and sources!
