This is an ON/OFF IR remote control module for Raspberry Pi 2/3 Model B or Pi Zero. It allows you to send power-on and power-off commands to your Raspberry Pi with a click of a button using the included remote control. This is a fancier way of powering the Pi on and off compared to plugging and unplugging the power cord.
NOTE: Please make sure that you have a 5 VDC / 2.5A power supply with this module. Also, do not connect your power supply to Raspberry Pi; connect the power cord into the power module instead.
