Introduction

The BenchDuiino is a development platform for building projects based on the Arduino, Raspberry Pi and PIC microcontrollers.  The platform defines a common foot print for processor and expansion boards to make it easy to expand the functionality of the system.  The BenchDuino motherboard includes many commonly used peripherals which can be connected to the CPU pins with jumper wires or plug in shunts.  The BenchDuino is an open platform and we encourage the development of plug-in CPU and expansion boards.
