The RAMBo 1.3 board is an all in one 3D printer motherboard. It is a full remix of the RAMPS design with the Arduino MEGA and stepper drivers all on one integrated PCB.

That is where the extreme and intense name stems from: RAMBo - (R)epRap (A)rduino-(M)ega-compatible (M)other (Bo)ard...definitely not the movie...

RAMBo is designed to work with the current RAMPS generation firmwares with minimal modifications to add firmware control of the digital trimpots and the microstep setting pins.

This product is RAMBo pre-assembled where you will receive all electronic components securely soldered to the PCB, ready for use. You will receive the endstop wires & switches of your choice, wires are complete with pre-crimped & housed ends.  Also included are the matching pluggable terminal blocks, two thermistor wires with pre-crimped & housed ends, a USB cable & we throw in gold connectors/headers for use on the motors & possible extra fan.
