This is a RipRap Controller based on Sanguinololu design, but with the ATmega644P microcontroller replaced by a mbed LPC1768 module
A prototype PCB has been assembled and functionally tested. With this done done software by bohn http://www.thingiverse.com/thing:11690 similar to the Sprinter firmware has been ported to the mbed module and is being tested for operation with a 3D printer.
The SprintBed PCB is plug compatable with the Sanguinololu PCB and uses the same Pololu modules. The 5V linear regulator has been replaced by a switching regulator, and a SD card connector is included.
