This bundle allows you to create your own Pi HAT by attaching custom circuitry. The PCB itself has a grid of 0.1” prototyping holes for attaching ICs, resistors, LEDs, potentiometers etc. The holes are connected on the underside of the board, which mimics solderless breadboard prototyping, so it's great if you're used to prototyping with breadboard.
An expansion prototyping board (plate) for Raspberry Pi model A and B boards (HCRASP0001). This board provides convenient screw terminals that allow for easier access to the Raspberry Pi's IO header. The board also includes a large prototyping area with a standard 0.1" pitch grid of gold plated pads....
