Pop this Prototyping Hat on top of your Raspberry Pi to give your circuits a super quick connect/disconnect from the Raspberry Pi. You can solder your projects directly onto the protoshield and pop them on/off your Raspberry Pi without any wiring! Useful for quickly swapping out your Raspberry Pi between projects.
These Pogo Pins are little spring-loaded contacts. Perfect for making momentary electrical contacts for testing jigs, JTAG programming or any other instance where you want to make a connection to a PCB contact without soldering connections onto the board.
