Xpresso Smoothie is an electronics package based on the LPCXpresso 1769, a development board using the LPC 1769, a powerful ARM Cortex-M3 processor running 120 MHz. It is also compatible with the mbed 1768, though at a small cost of speed and features. It has been developed with the Smoothie firmware in mind. The package is still in development, and has not been manufactured yet, but should be in the coming weeks.

Full Feature List
- 12V or 24V compatible
- 6x endstops, 3 with on-board opto circuitry
- 5x headers for Pololu-style stepper drivers
- 4x MOSFET power outputs, two of which are fuse protected for bed and extruder
- 3x thermisors
- Integrated MicroSD reader
- Breakouts for I2C, ADC: 1 pin, GPIO: 3 pins, and on-board Ethernet
Differences when using mbed
- Only 3 endstops, no on-board opto circuitry
- 4 axes
- 3 power outputs
- Breakouts only for I2C and Ethernet
- Slightly less powerful chip, 96 MHz instead of 120 MHz.
Current Status
Schematic and layout is nearly complete. Fabrication of PCB will happen soon, followed by documentation of assembly, and making this wiki page a little nicer.
