Major Features:

  • 4 x integrated genuine Trinamic TMC2130 1/256th microstep motor drivers with layer shift detection, faster and silent printing.
  • 4 PWM Mosfet outputs
  • 3 thermistor inputs + ZProbe thermistor, SPI (Serial Peripheral Interface) communicated motor current control (no tiny knobs to tweak)
  • SMPS supports hostless printing on power supply voltages from 10-24V DC
  • 2 fuse protected power rails (Heated Bed, 15A, and Primary Power 10A 10-24V: Motors & Logic (5A dedicated fuse) + Extruders, Fans (5A dedicated fuse))
  • High quality connectors


Einsy Rambo is designed to work with the current RAMPS generation firmwares with minimal modifications to add firmware motor current control and the microstep setting.

You can simply use the Arduino IDE with Rambo Addons and set board to "Rambo". There is an Arduino plugin folder on github that exposes additional pins in the Arduino IDE.


Recommended Power supply 12V-24V DC, 16A+.
