Adafruit Perma-Proto

To kick off the Adafruit HAT party, we have this plug-in expansion board inspired by Perma-Proto. It features a grid of 0.1" prototype solder holes for connecting chips, resistors, LEDs, potentiometers, and more. The holes are connected underneath with traces to mimic the solderless breadboards you know. Additionally, there are long power rails for +3V, +5V, and ground connections to the Pi. Near the top, we break out almost every pin you might want to connect to the Pi (Pin #26 didn't quite make it).

This is just the base version of our Perma-Proto HAT. It comes with a PCB and a single 2x20 GPIO header for Raspberry Pi, allowing you to place your Perma-Proto on top of your Raspberry Pi (like a nice little hat). This version does not include EEPROM, so you can "stack" it with other HATs without worrying about an EEPROM address collision.

You can customize your Perma-Proto setup with a standard 2x20 stackable header or an extra tall 2x20 stackable header. You can also replace the 2x20 header with a slim 2x20 type if you want it to sit closer to the Pi, or with an extra tall one if you want it to sit above the USB/Ethernet ports. A little light soldering is required to attach the header to the PCB, but it's simple work. This little hat is only compatible with the Raspberry Pi A+, B+, or Pi 2. It does not work with the Raspberry Pi Model A or B.
