Overview
Power Shield is a portable offline power supply board for Arduino. Using two AAA batteries and with high-efficiency DC-DC boost circuit, this shield is the power source which can output 5V/350mA. Standard Arduino pin map makes it compatible with Iteaduino series and other Arduino compatible board.
Features
- Up to 90% high-efficiency boost circuit
- 5V/350mA output
- Power supply for external USB device with cable
- Operation temperature: 0℃ ~ +60℃

Hardware
Installation
Two AAA batteries can be installed on Power shield. When the switch is set to ON, this shield can output the 5V voltage, and when the switch is set to OFF, the output is cut down.
On this shield, there is a standard USB A socket which can supply a 5V/350mA for external USB device.
Indicator LED
The shield contains a LED:
- PWR: indicates the voltage output.
