   - On the board is a power MOSFET that can be powered from the board or via an external power source. It can also turn external devices on and off via an output of the microcontroller if they  require larger currents (e.g., light bulbs or electric motors).   - On the board is a power MOSFET that can be powered from the board or via an external power source.

   - The board is as well prepared for stand-alone operation without the USB cable: All you need to do is to solder a clip connection for 9V batteries, a switch, two capacitors and a 5V regulator on the board.   - The board is as well prepared for stand-alone operation without the USB cable: All you need to do is to solder a clip connection for 9V batteries, a switch, two capacitors and a 5V regulator on the board.
