Breadboard Overvoltage Protection Module
This is a breadboard friendly power overvoltage protection module. The protection voltage limit is jumper selectable for 3.3V or 5V. If the input voltage exceeds the limit then the output is disconnected from power. Use it to protect sensitive components from damage due to overvoltage.

This is not a voltage regulator; this goes after the voltage regulator or buck/boost power module. It protects your components in the event of a power supply regulation failure or connection to the wrong power supply.
