RepRap Prusa Mendel 3D Printer Diy Kit , Mendel Teensylu v0.8 Hi3D
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 design - 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)
Logic & Motors supplied by ATX power supply (needs molex harddrive
connector, and optional 4pin atx connector for additional 12v)
Motors supplied by 5mm screw terminal 7-35V
Logic supplied by USB bus
Logic supplied by optional on-board voltage regulator (molex
harddrive connector cannot be installed at the same time)
on-board USB connectivity
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
4 endstops including 4th stop called E-Stop to be used as an
emergency stop, or extruder stop (to be added in firmware).
14 Extra pins available for expansion and development - 6 analog
and 8 digital (Fully compatabile with Sanguinololu), with the
following capabilities
