Design your own Pi HAT, attach custom circuitry, and otherwise dress your Pi Zero, A+, B+, Pi 2, Pi 3, and Pi 4 (any Pi with a 2x20 connector) with this jaunty prototyping HAT kit.

To kick off the Adafruit HAT party, Adafruit has this Perma-Proto-inspired plug-in daughter board. It has a grid of 0.1" prototyping soldering holes for attaching chips, resistors, LED, potentiometers, and more. The holes are connected underneath with traces to mimic the solderless breadboards with which you're familiar. There are also long power strips for +3V, +5V, and Ground connections to the Pi. Near the top, it breaks out nearly every pin you could want to connect to the Pi (#26 didn't quite cut).

This is just the basic version of Adafruit's Perma-Proto HAT. It comes with a printed circuit board and a single 2x20 GPIO Header for Raspberry Pi to put your Perma-Proto on top of your Raspberry Pi (like a nice little hat...) This version does not come with an EEPROM so you can 'stack' it with other HATs without worrying about an EEPROM address collision.

You can customize your Perma-Proto setup using a standard 2x20 stacking header or an extra tall 2x20 stacking header. You can also swap out the 2x20 header with a slim 2x20 type if you want it to sit closer to the Pi, or an extra tall one if you want it to sit above the USB/Ethernet ports.

A bit of light soldering is required to attach the header to the PCB but it's easy work.

This hat is only compatible with the Raspberry Pi Zero/A+/B+/2/3/4 (any Pi with a 2x20 connector)! It will not work with the Raspberry Pi Model A or B with a 2x13 connector.

Ada fruit's initial version has the +3V and +5V markings in blue, and the GND markings in red, future orders will have these colors swapped to better match a solderless breadboard
