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 capabilities.
The Re-Arm micro controller board is more powerful and built with a faster processor, enabling faster feed rates for you 3D printer. The board has an SD card slot for firmware and configuration files, but also supports a second SD card connected via an LCD screen for project file loading. Having a separate configuration file outside of the firmware makes settings changes much easier than other boards which require new firmware for any and all settings changes. The configuration is a text file, making changes from a computer easy and fast.
More powerful, faster processor enabling faster feed rates for you 3D printer.
Easy to manage configuration using a text file on SD card. Other controller boards require freshly uploaded firmware with every settings change
Since SD cards appear as a drive in windows, it's easy to drag and drop new firmware or edit the config file right on your computer without the need for specialized software.
Capable of running smaller micro-step stepper drivers such as the 1/128 micro-stepping SD6128 driver, available as an addon item.
Headers for an Ethernet RJ45 add-on Module, which is not included with this board.
Utilize a graphic LCD screen on your Delta 3D printer without issue.
Supports 2 SD cards - one for settings and firmware, installed directly onto this board as well as another for file loading, which connects on the LCD screen.
5V tolerant pins, except for analog inputs which are 3.3V
Filtered endstop inputs.
Able to run CNCs, Laser cutters and 3D printers.
