Adafruit Perma-Proto HAT for Raspberry Pi Mini Kit - With EEPROM

Design your own Pi HAT, attach custom circuitry and otherwise dress your Raspberry Pi with this jaunty prototyping HAT kit with EEPROM

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 nearly every pin you could want to connect to the Pi is broken out (#26 didnt quite make the cut).

This is the fancier 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 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.
