3D Printer Teensylu V0.8 Hi3D RepRap Prusa Mendel Control Board
3D Printer Teensylu V0.8 Hi3D RepRap Prusa Mendel Control 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: Size: 100 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 Pololu stepper driver boards on-board (X, Y, Z Extruder) Supports multiple power configurations: Logic & Motors supplied by ATX power supply (With ATX-4 12V 25A power) Motors supplied by 5mm screw terminal 7-35V Logic supplied by USB 5V With 2 thermistor connectors With 2 N-MOSFETs for extruder/bed heaters With 1 low power MOSFET driver fan Selectable 12v/5v endstop voltage With 4 endstops including, the 4th E-Stop to be used as an emergency stop 14 Extra pins available for expansion and development. 6 analog and 8 digital (Fully compatabile with Sanguinololu) with the following capabilities UART1 (RX and TX) I2C (SDA and SCL) SPI (MOSI, MISO, SCK) PWM pin (1) Analog I/O (6) Package included: 1 x 3D Printer Teensylu V0.8 Hi3D RepRap Prusa Mendel Control Board
