Raspberry Pi Model A+ Review

2) Pi Jumper and Pi Jumper Plus breakout boards – stacks on top of the Raspberry Pi

Pi Jumper sits nicely on the Raspberry Pi Model A+ … and worked right away, including the 3v3 and 5v I2C ports.

You can see the Edimax WiFi stick and micro USB power cable I used for testing in these shots.

Pi Jumper Plus  required a stacking header between the IDC cable and the Raspberry Pi Model A+’s 40 pin GPIO header, but other than that, it just worked!

As a matter of fact, I am sure that Pi Jumper would work with a non-stacking female header with the Model A+

3) Pi Rtc DIO – Real Time Clock, I/O expander & prototyping board

As I expected, Pi Rtc Dio (Mikronauts latest add-on for the Raspberry Pi) also just plugged in and worked, adding 32 digital I/O’s and a real time clock to the Model A+ (not to mention a nice prototyping area)

As you can see below, it mounted nicely on the first 26 pins of the 40 pin GPIO connector.

4) EZasPi  prototyping board – stacks on top of the Raspberry Pi

As you can see, EZasPi also fits – however the mounting holes are for the rev.2 boards, and due to the new mounting holes, the header is offset about 9mm.

This particular EZasPi had a 170 point breadboard and female pin sockets on it, I use it for quick prototyping on top of Pi’s.
