Raspberry Pi with Custard: Interfacing to the Raspberry Pi GPIO Using the Custard Pi range of add-on boards

The Raspberry Pi is a single board computer aimed at encouraging students and hobbyists to experiment with programming. It has a GPIO connector for controlling external devices,

The Custard Pi range from SF Innovations provides the student and hobbyist a way of getting the most out of the GPIO. For example the Custard Pi 6 has 8 relay cards for switching loads ON and OFF. Upto 8 of these can be daisychained to control a maximum of 64 loads.

This book provides a detailed circuit description of the entire range. It also supplies test Python code to enable the boards o be tested and give the user some initial experience of how to use them. It also has some applications which can be used as student projects.
