As you surely know Raspberry released his Model B+ board last July. We have been testing it with our Raspberry Pi to Arduino Shields Connection Bridge during last week, to ensure its full compatibility.
Just in case you didn't know this product, the idea behind our bridge is to allow to use different shields, boards and modules designed for Arduino in Raspberry Pi. It allows also to connect digital and analog sensors, using the same pinout of Arduino but with the power and capabilities of Raspberry.
We created also the arduPi library which allows to use Raspberry with the same code used in Arduino. In this library you can find conversion functions to control all the I/O interfaces in the same way as in Arduino.
As we can see in Raspberry official website (check the link, the upper block is exactly the same as in model A/B. You may remember some changes were made in this part in the past. We are working with revision 2, as we guess the vast majority of you. Accordingly, the main change is Raspberry B+ includes more GPIO (14 pins more). See picture below.
As the former pins remains unchanged, and the GPIOs are the same, our shield connects with the board with no problems. At the end, we are very happy with the testings we have made. We have tested many of the eHealth sensors (the patient Position Sensor - Accelerometer, and the body Temperature Sensor, for example, and we do not foresee any problem for this side) and also with interruptions.
More changes we love: the new Micro SD (the old card socket broke easy and frequently), the video onto the 3.5mm jack (one jack for audio and video), the lower power consumption and the extra USB ports.
You can still install Raspbian - it is the default operating system, and we usually choose it. Model B+ is recommended for use in schools: it has more flexibility for learners and more USB ports than any other model.
Our Raspberry Pi to Arduino Shields Connection Bridge works perfect with the new board (you can get the new Raspberry Model B+ board here).
Why don't you give the Connection Bridge a try?
