Summary
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 120M Hz. 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 months.
Features
- 5 Pololu-style stepper drivers
- 4 MOSFET power outputs, two of which are fuse protected for bed and extruder
- 3 thermisors
- 6 endstops
- 12V or 24V compatible
- Integrated MicroSD reader
- Breakouts for I2C, ADC, 3 GPIO, and on-board Ethernet chip
Current Status
Schematic and layout is nearly complete. Next steps include verifying pinouts with a breadboard test of the LPCXpresso, sending board out for fabrication, documentation of assembly, and making this wiki page a little nicer.
