It's a handy power-breakout, featuring barrel-jack input, and multiple 5V regulated, unregulated, and USB-compatible power taps.
It looks like a generic power board, and it is. And it's surprisingly useful one at that.
Feed it 8~20VDC in, and then get convenient 5V access through 8-pairs of +/- pins, and a USB jack configured with bias resistors for "iDevice" charging. And there's taps for 4 pairs of unregulated (Vsource) power. With a power switch.
Besides being a handy project power-supply, we've successfully used it as a remote power center for a Synapse Radio / Star Controller demonstration board, which it was ideal for. We pushed 12V into the power board, sent the regulated 5V to the logic controller board, and passed the 12V directly to the LEDs, all from the same board. AND we still had the USB A power jack for powering an Arduino demonstration.
This unit is modifiable for additional performance - add a bigger heatsink for supplying higher current. Or replace the IC for different voltages, or to utilize a high-efficiency switching voltage regulator!
