Description :

Simple breadboard power supply kit
Takes power from any USB port and outputs a fuse protected and regulated 3.3V
.1″ headers mounted on the bottom of the PCB for easy insertion into a breadboard
Pins labeled 5V/GND, 3.3V/GND plug directly into the power lines
Be aware of unused power and ground pins shorting when inserted into a breadboard row
Orient the board to avoid shorting or utilize both 5V and 3.3V at the same time
USB v2.0 specifies max of 500mA at 5V and on-board fuse limits the current to 500mA
Has a convenient On/Off switch
Comes as a bag of parts kit, requires assembly with a soldering iron and basic soldering skills
Resistor sizes can be determined by reading resistor bands or using a multimeter.
