This module can take input either from three wire center tapped transformer or DC supply and output regulated voltage at 1.5 ampere. It has 4 diodes bridged that convert swinging AC voltage to DC voltage. This is ideal for running motors or any other heavy load. When output supply is adjusted using the potentiometer led brightness also varies. It can supply maximum of 25v X 1.5a = 37.5watt

Secondly we have LM2576 based switching power supply breakout board. Its all the same like the above except it only takes DC input and can provide much higher output power, 16v X 3a = 48watt.


Finally we have triple axis Magnetometer breakout board, it can sense heading direction and spits the same information through I2C protocol. Good for navigation related project. It comes soldered with SCL & SDA line pull up resistors, so just connect your microcontroller SDA and SCL pin and start communicating with this.
