***Optical Endstops are currently unavailable. We are working on a new design & will have them available again soon.***

This is RAMBo v1.2gp. The RAMBo board is an all in one 3D printer motherboard. It is a full remix of our RAMPS design with the Arduino MEGA and stepper drivers all on one integrated PCB. That is where it got the name RAMBo - (R)epRap (A)rduino-(M)ega-compatible (M)other (Bo)ard.

Major Features - 5 x integrated 1/16th microstep motor drivers, 5 PWM Mosfet outputs, 4 thermistor inputs, digital trimpot(no tiny knobs to tweak), SMPS supports hostless printing on power supply voltages from 10-24V DC, 3 independent fuse protected power rails, LUFA USB, high quality connectors, did I say hacker friendly ...

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.

Additional information and sources at RepRap.org/wiki/RAMBo.   This board is Open Source Hardware licensed GPLv3, so please use, copy, improve, hack, upgrade, and / or contribute.

Recommended Power supply 12V-35V DC, 16A+.

Linux and Mac use CDC interface and have hardware driver built in.
Windows hardware driver: RAMBo.inf

Includes all power connectors, crimp contacts and housings for thermistors and motors and pre-crimped wires for endstops.

A preconfigured Marlin Firmware is preloaded onto the board. To re-flash this board, you can simply use the Arduino IDE and set board to "Arduino Mega 2560". There is also a Arduino plugin folder on github that exposes additional pins in the Arduino IDE.

Designed and assembled in USA by Ultimachine.
