Design your own Pi HAT, attach custom circuitry and otherwise dress your Pi A+, B+, or Pi 2 with this jaunty prototyping HAT kit with EEPROM
To kick off the Adafruit HAT party, we have 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’s also long power strips for +3V, +5V and Ground connections to the Pi. Near the top we break out nearly every pin you could want to connect to the Pi (#26 didn’t quite make the cut).
This is the fancier version of our Perma-Proto HAT. It comes with a printed circuit board and a single 2×20 GPIO Header for Raspberry Pi to put your Perma-Proto on top of your Raspberry Pi (like a nice little hat…) This version comes with a blank 24C32 I2C EEPROM soldered on and connected to the EEDAT/EECLK lines so you cannot ‘stack’ it with other HATs . However, you can program in the EEPROM to make a self-identifying setup using the Pi Foundations’ HAT specs – please note the specifications are still under development.
You can customize your Perma-Proto setup using a standard 2×20 stacking header or extra tall 2×20 stacking header . You can also swap out the 2×20 header with a slim 2×20 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 A+, B+, or Pi 2! It will not work with the Raspberry Pi Model A or B.
Our 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
