Details

The regulated power supply accepts unregulated intputs from 9V to 15V AC or DC and gives regulated output of 5V and 3.3V suitable for microcontroller projects which needs precise voltage to work. The input can come from power transformer or wall mount DC adapter. Since board has diode bridge input polarity does not matter.

All outputs are brought to screw terminal. There is also an Unregulated output voltage to drive high current loads like relays and motors.
