Mini 3.3V+5V USB power supply board

  • $2.95

Will be in stock after

This is a tiny board with a 3.3V regulator, barrel- and mini-USB connectors.  It provides a 3.3V output as well as passing through the 5V received from the USB connector (or whatever voltage between 5 and 12V you input on the barrel connector).

The header comes included so you can solder it onto either side of the board - bottom side is great for plugging directly into a breadboard, while topside is great for jumper lead connections.

It uses an AMS1117 3.3V regulator (datasheet here) which can supply a current of up to 1A.

Output header:

  • GND
  • ID, D+ and D- (USB connection passthrough)
  • +5V
  • +3.3V
