The GR712RC development board has been designed to support the development and fast prototyping of systems based on our GR712RC dual-core 32-bit fault tolerant LEON3FT SPARC V8 processor.

The GR712RC development board comprises a custom designed PCB in a Double Eurocard format (233.5 mm x 160 mm) making the board suitable for stand-alone bench top development, or suitable for mounting in a housing. The principle interfaces and functions are accessible on the front and back edges of the the board.

The GR712RC device incorporates an internal programmable switch matrix which means that the same input/output pin can be used for multiple functions. This board therefore has a large number of configuration features in order to be able to exercise and configure the functions of the device.
