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 hat is only compatible with the Raspberry Pi Model A+ or B+.
It will not work with the Raspberry Pi Model A or B.

Hackaday branded Perma-Proto Black Hat. Design your own Pi HAT, attach custom circuitry and otherwise dress your Pi A+ or B+ 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 we break out nearly every pin you could want to connect to the Pi (#26 didnt quite make the cut).

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.

The A+ was spotted in the wild over the weekend, only for a product page at Element14 describing the computer to disappear.

RS Online’s Australian site listed the A+ in the wee hours of the British morning at a price of AU$41.00. (US$35.56, £22.37 and €24.48). The A+ has since appeared on RS Online’s UK site at an even £20.00.

That makes the A+ just about a clone of the B+, save for the amount of RAM – the A+ has 256MB compared to the 512MB on the B+ – and in terms of size.

The arrival of the A+ doesn’t mean the end of the model A. Pi founder Eben Upton wrote to tell us “The big news is that we’ve cut the price to $20 from $25 for the old Model A.”
