From the shop's description

3D printer Prusa i3 MK3 integrated motherboard Einsy Rambo 1.1b with driver TMC2130*4 For Arduino MEGA compatible Atmega2560 and Atmega32u2 processors are compatible with all RAMPS class firmware Crystals for both usb and mcu (timing accurate to 10ppm) 3 Thermistor jacks + 4th Thermistor circuit on ZProbe. Motor Drivers 4 Trinamic TMC2130 1/256th microstep motor drivers(2 connectors on Z for Prusa Mendel and other dual Z printer designs) SPI Control of stepper current instead of PWM. Microstep mode configured by MCU through firmware (SPI, no jumpers needed) PWM DC outputs (Extruders, Fans, Etc.) 4 outputs (1 Extruder, 1 BED, 2 low power (fan, etc.) Low resistance mosfets for cool running Indicator led for each channel FANS have 3pin fan connector. FANS have 5V instead of 12-24V power source. FAN connectors have tachometer feedback pin to the MCU to measure fan speed in capable firmware. Power 2 power input rails Heated Bed, 15A 12-24V (15A dedicated fuse) Primary Power 10A 12-24V: Motors, Logic & Fans (5A dedicated fuse) + Extruder (5A dedicated fuse) Built in SMPS for 5V generation from the Motors, Logic & Fans rail Provides 5V power to FANS Connectors 4-pin motor, zprobe plug-Molex 5057-9404 3-pin fan plug-Molex 5057-9403 2-pin thermistor, mech. endstop plug-Molex 5057-9402 Package Includes: 1x EinsyRambo 1.1b 1x USB Cable 1x 4pcs black heat sink Related Products: CNC | 3D PRINTER PARTS ons:
