Re-Arm Clone 32 bit 3D Printer mainboard


Out of stock



RE-ARM is a 100Mhz, 32-bit ARM controller with the popular Arduino MEGA footprint. It’s a plug-in replacement for the Arduino Mega in your RAMPS setup for a quick and easy upgrade to 32-bit goodness.

Detailed Specs (running RAMPS)

100Mhz, 512kb Flash

Mini B USB

3.3V system voltage

10-30V power supply input range, using Vin pin or barrel jack

1 Heated bed, 2 Hotend Mosfet drivers

SD card slot for firmware upgrades and config file

6 End stops, with filter and pull-ups

3 thermistor inputs

Support SPI Displays like Viki2 and mini Viki(direct) and RRD Graphic LCD(adapter)

Support for I2C and parallel character LCDs using universal adapter by Jim Morris

Header breakout for Ethernet module (RJ45) daughter board.

What are the benefits of using re-ARM?

1.More powerful processor. Faster feed rates!

Runs Marlin 2.0 or Smoothieware.

2.Easy configuration using a text file on SD card, no need to upload firmware every settings change

3.SD card appear as a drive in windows. Easy drag and drop new firmware or edit config file.

4.Capable of running smaller micro-step stepper drivers. Like the 1/128 micro-stepping SD6128 driver.

5.Available Ethernet RJ45 add-on Module

6.Run graphic LCDs with your Deltas without hiccups.

7.Run 2 SD cards, one for settings and firmware(on board) and the other for file loading (on LCD).

8.5V tolerant pins, except for analog inputs which are at 3.3V

9.Filtered endstop inputs.

10.Able to run CNCs, Laser cutters and 3D printers.
11.The power chip uses the dc wide voltage input, which can adapt to a variety of power supply voltage. The voltage input range is 4.5v – 36V, and the maximum current is 1.2A.

Important notes.

We use Marlin 2.0 exclusively and have not tested this board with Smoothieware.

We only recommend Sandisk for SD media and strongly suggest you only store the firmware file on the internal SD card.
