Main components
2README
README.mdPi-Power
Simple 3 Amp power supply board to power the single board computer over GPIO. Input should be between 9 and 24 VDC.

Board breaks out SPI and I2C, and provides some 5V 2.54mm headers toward the bottom and some general proto area in the middle.
Simple word of warning:
Do not stick your fingers into this circuit while it's powering something you care about. Your fingers have a resistance value, and will change the feedback network regulating the output (R2,4), and/or bridge the compensation circuit (R3,C4) potentially causing a power surge to the board. Follow typical electrical rules, don't stick your hands into live power supply circuits.
