The Gertbot is an add-on board made especially for, and compatible with all versions of the Raspberry Pi. By plugging the Gertbot to your Pi GPIO header, you are able to control and drive various motors such as stepper and brushed motors. The Gertbot can also be used as a standalone board and can be controlled from any computer via a UART serial port.
The Gertbot brings electric power to your Raspberry Pi. It has four channels each capable of driving 30 Volts and 2.5A. It can drive capacitive or inductive loads. Besides the four H-bridges the boards also has two open drain N-MOSFETS which can sink 3A at 30V.
The primary target is driving motors. Stepper motors, brushed motors and other robotics, however it can just as well be used to control other equipment where a lot of electrical power is required. For example one channel can drive 10.000 LEDS. Use three channels for RGB and combine that with the build-in PWM controller: you have mood lighting for a whole building. Anything which requires between 8 and 30V and up to 10Amp it can drive it! Altough the board plugs on top of a Raspberry-Pi it can also be used standalone and controlled from Windows or any other computer with a serial port.
