An open source hardware kit for the Makers in India.

The BreadBoard Power Supply fits right into your BreadBoard and powers its rails with either 5V or 3.3V.
After it is fully assembled, it can easily connect to the power rails of a standard 840 tie-point Bread Board. It takes its input from a standard wall adapter supplying 6 – 12V into the DC Jack of the PCB. And provides a regulated 3.3V or 5V output from a power selection jumper. The PCB is fully labeled and includes names and values of all the components needed and has a very High Quality RoHS Compliant Lead-Free finish.
