Product Description

Speedy is a stepper motor controller based on the awesome open source hardware CNC controller board SmoothieBoard. Speedy was developed as a request from RoboBeast and RepRAP Morgan. They required 32 microsteps / step with fast decay.  The board is based on an NXP LPC 1769 32bit Cortex-M3 running at 120MHz.

The PCB layout was completely redesigned including some subtle changes.

The stock SmoothieBoard firmware is used.

  • Drag and drop firmware updates.
  • Config changes via USB – no firmware tweaking.
  • USB composite – CDC serial and Mass storage.
  • Ethernet control – for PC-less printing.
  • Micro SD.
  • 8 Mosfet outputs – 4 x low current and 4 x high current.
  • 8V – 24V.
  • 4 Thermistor inputs.
  • 6 End stops – 3V3 or 5V.
  • I2C, UART, SPI break-out connectors.
