AdaAdafruit Perma-Proto HAT for Pi Mini Kit - No EEPROM-2310fruit Perma-Proto HAT for Pi Mini Kit - With EEPROM-2314
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 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 2x20 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.
