Specification:
Item Type: 3D Printer Accessories
Motor Drive:
4 Trinamic TMC2130 1/256 microstep motor drivers (2 connectors on Z for Prusa Mendel and other dual Z printer designs)
The SPI controls the step current instead of the PWM.
Micro-step mode (SPI, no jumper required) for MCU configuration via firmware
PWM DC output (extruder, fan, etc.)
4 outputs (1 extruder, 1 BED, 2 low power (fan, etc.)
Low-resistance mosfets for cool operation
Indicator light for each channel
The fan has a 3-pin fan connector.
FANS uses a 5V instead of a 12-24V power supply.
The tachometer's tachometer feedback pin is connected to the MCU to measure fan speed in powerful firmware.
Power:
2 power input rails
15A 12-24V heating bed (15A special fuse)
Main power supply 10A 12-24V: motor, logic and fan (5A special fuse) + extruder (5A special fuse)
Built-in SMPS for 5V from motor, logic and fan rails
Provide 5V power for FANS
Connectors:
4-pin motor, zprobe plug - for Molex 5057-9404
3-pin fan plug - for Molex 5057-9403
2-pin thermistor, mechanical. Stop plug - for Molex 5057-9402
Features:
1EinsyRambo 1.1a motherboard for Reprap Prusa i3 MK3 with 4 for Trinamic TMC2130 stepper drives SPI to control 4 Mosfet switch outputs. 2For MEGA compatible Atmega2560 and Atmega32u2 processors, it is compatible with all RAMPS type firmware. 3Crystal for USB and MCU (timing accurate to 10ppm) 3 thermistor jacks on the ZProbe + 4th thermistor circuit. 4The tachometer's tachometer feedback pin is connected to the MCU to measure fan speed in powerful firmware. 5The builtin SMPS generates 5V from the motor, logic and fan rails and 5V to the fans.
