4, Mechanical & Electrical:

To the board there are some wiring to do and change of jumpers.

Mechanical:

My plan is to install it inside the EQ6 mount. I replace the original lid with a 3D-printed one. Something like this, I have to add some towers on it where I can screw the circuit board to. Add openings in the chassi for the USB B connector, power switch, power inlet and a led.

When studying the board I see the connectors to the stepper motors, looks very like the connectors on the EQ6's stepper motors. Maybe I can use them as they are.

Electrical:

The internal USB connector must be attached to an USB B panel mount. But there isn't space enough for the USB house. I can instead connect it to the 5 pin connector. Then I need a cable like this.

Here is a link to one who is doing something similar with a EQ5 mount:
