Geeetech 3D Printer Parts Teensylu V0.8 Board Hi3D RepRap Prusa Mendel Printer Driver Board
Description:
This is a project that is based on Sanguinololu. The ATmega644P has been replaced with an Atmel AT90USB1286 MCU. This Microcontroller has on-chip USB, removing the need for the FTDI USB UART. LUFA CDC bootloader preinstalled on the AT90USB1286 allows you to upload the firmware through USB cable directly. All of the through hole resistors and capacitors have been replaced with 0805 SMT components. Like the Sanguinololu the Teensylu has expansion headers supporting I2C, SPI, UART, and ADC pins. All extra I/O ports of the AT90USB have been broken out to headers for prototyping.
Features:
- Small volume - board is 100mm x 60mm
- Teensylu clone, Atmel's AT90USB1286
- LUFA CDC bootloader preinstalled on the AT90USB1286 allows you to upload the firmware through USB cable.
- Up to 4 A4988/4983 stepstick or Pololu stepper driver boards on-board (X,Y,Z,Extruder)
- Supports multiple power configurations (Carried from Sanguinololu)
- 2 thermistor connectors with circuitry
- 2 N-MOSFETs for extruder/bed heaters
- 1 N-MOSFET for low power fan or motor
- Selectable 12v/5v endstop voltage
- 14 Extra pins available for expansion and development - 6 analog and 8 digital (Fully compatabile with Sanguinololu), with the following capabilities
- Additional 14 pin header with 11 I/O for prototyping
- SMT Components sized at 0805 for easier soldering
Package included:
- 1 x Printer Driver Board
