The Gertboard[sup]TM[/sup] is an add-on board that extends the use of Raspberry Pi to devices in the real world, including motor/lamp control, and the sensing of voltages and currents. It also contains a host micro that can be programmed with code written and compiled for it, on the Raspberry Pi. The Gertboard[sup]TM[/sup] Kit contains the bareboard PCB and electronic components that allow you to self assemble your own Gertboard[sup]TM[/sup].
It comes with a large variety of components, including buttons, LEDs, A/D and D/A converters, a motor controller, and an Atmel AVR microcontroller. There is a suite of test/example programs for the Gertboard[sup]TM[/sup], written in C. , which is freely available from below Design Elements. The Gertboard[sup]TM [/sup]Kit is supported by a number of videos featuring Gert van Loo, creator of the Gertboard[sup]TM[/sup] and Paul Gibbon from Weller. These video materials demonstrate how to solder through hole and surface mount components onto the Gertboard[sup]TM[/sup].
