Power supply

Turn on/off your 3D printer remotely through your Octoprint interface or make your own custom application. The best part? You don't need a power supply adapter for your Raspberry Pi. Plug it into the mains outlet and it is ready to go.

Fan support

Mount a 40mmx40mm fan directly on the PCB. The 4 pin header can provide 5V suppply, speed control through the Raspberry Pi and RPM read-out.

Serial port

Serial to USB converter dedicated for communicating with your 3D printer. The 5V pin is disconnected to prevent back powering your 3D printer. You don't need to make any modifications to your USB cable by yourself anymore.
