His solution is to add a P channel MOSFET which only allows power to flow when the polarity of the source voltage is correct. The schematic above shows the P-FET on the high side of the circuit.
The SparkFun MOSFET Power Switch and Buck Regulator (Low-Side) combines two circuits into one board: an LMR14203 buck regulator configured to output 3.3V and an N-channel MOSFET (PSMN7R0-100BS) ...
Do you want to avoid having multiple power adapters for your project and your Arduino? The MOSFET Power Switch is one of those products that we needed ourselves at SparkFun, so we figured other folks ...
