This appears to be a special purpose motherboard or daughter card. I do not know what brand of mircocontroller it is based on, but it looks like it simply converts RS485 TTL serial commands into step and direction commands that must still go to stepper driver power boards/chips. It has some very nice sounding pre-installed software to do positive and negative limit stops, acceleration and deceleration, peak velocity, and linear movement and even helical movement in several axes at once.

But basically it does something fairly close to what the Mendel motherboard does. Take gcode commands from a host computer and convert them to stepper steps and directions, and sense limit stops. Sounds like they may do it better, but you will still need all the stepper and extruder driver boards.

It's based on LPC2136/01 microcontroller.

The detail info is here:

The communication language is not G-Code, but something similar to what's being used in conventional controllers. And it could talk binary - to save microcontroller's parsing/converting time.

There is a G-Code wrapper relized externally (open source) that currently supports this set:

G0, G1, G2, G3, G4,
G17, G18, G19,
G20, G21, G28,
G61, G61.1, G64,
G80, G81, G82,
G90, G91, G92,
M2, M3, M4, M5, M6, M7, M8, M9,

For what it is that's expensive.
