If there’s one thing the RasPi may have been missing for the hobbyist crowd, it was an extensive interface system and microcontrollers. Well, the folks that are looking for such functionality will be pleased to hear that Gert Van Loo, designer of RasPi’s alpha hardware, has created an add-on board for just that.
The Gertboard includes motor controllers, A/D and D/A converters, and even has an Arduino chip built in. It connects via the GPIO ports on the RPi itself, so it doesn’t take up any of the standard I/O ports.
The Gertboard will be sold exclusively through element14, and will cost a mere £30 ($50). You can pre-order one now, and the delivery window is currently listed as mid-September.
