More info on the Re-ARM board. Disclosure: I have one for evaluation, and it’s amazing. That’s my honest evaluation. I’m planning on backing and buying more when possible.

Re-ARM details.
The Re-ARM is basically designed for the RAMPS and machine control in general running smoothie. Most of the usable pins of the LPC chip are broken out including the Ethernet/LAN pins.
The Re-ARM can take up to 30V input but we all know some RAMPS can only do 16V due to component voltage limitation, others can do 24V no problem.
On-board mSD card slot for config file and firmware updates
DC jack for external supply
USB mini B with ESD protection ( USB A shown on prototypes)
LAN daughter board available
What works on the RAMPS.
All 3 heaters ( 5V gate drive)
All 6 endstops ( with RC filter on each pin)
All 3 thermistor inputs ( also available on separate pins using analog GND)
All 5 drivers
Servo pin ( 5V signal)
Viki2 , mini Viki and RRD graphic GLCD works ( Character LCDs needs an adapter)
Some expansion pins on the RAMPS are available but not all are connected. A bunch of expansion/free pins are available on the Re-ARM.
Thinking of making custom shields? A diagram showing pin designations is in the works.

This sound promising. But it will be really awesome if we have one shield that support CNC and 3D prints so we will be able to build modular switch between CNC and 3D printer.
Sorry, just trying to keep up…so the Re-ARM will be a drop in replacement for the Arduino Mega 2560 board? It will accept the RAMPS shield for all the connections to the printer? That does sound like a nice way to upgrade an existing printer to 32 bit and smoothieware.
@kenneth_rooks , I suspect it’s going to cost somewhere close to a legitimate Arduino Mega, probably around $65. Might be a little higher. That’d be a steal to get up to 32bit and smoothieware. They take concerted effort to ensure that their step pulse generation is smooth, and their configuration allows such an incredible amount of flexibility.
It’s at times like this I hate the $ to £ exchange rate currently. Does look damn good. Did I read correctly that the RRD Full graphic needs a break out or is it the Standard RRD display?
