rPower Module

The rPower module is used primarily to power uMMC, uMP3, and rMP3 boards in systems which need external power to operate those modules. It provides a regulated +5VDC output.

The supply power for the rPower module can be from +7.5VDC to +12VDC, often from a wall wart, so a 2.1mm barrel jack is provided. The barrel plug must have a positive tip.

The only pins on the rPower that are of interest are:

• V = +5V regulated (from 7805 regulator)
• G = Ground

(V and G pins can be found on the two 7 pin side connectors)

• + = 7.5VDC → 12.0VDC positive input from supply
• - = Ground input from supply
