Converting this schematics into a dual sided PCB was a piece of cake! The only "trick" was to use the PCB to support the DB25 connector. The thickness of the PCB is just perfect to fit between the two rows of the connector. One row on top face (red) the second on bottom face (blue).

This PCB was sponsored by PCBWay (thanks for that!). You can get yours following this link: CNC controller board PCBway

The quality of this PCB is, as usual, excellent. 

The only important parameter when ordering is "thickness". Don't change the default value of 1.6mm

With this value the PCB will fit perfectly into the DB25 connector pins.

The ESP32 lolin Lite board is mounted in "Mezzanine" above this shield, the result is a very compact device that can be powered by a USB cord connected to the PC. (alternatively I added a 5V connector, but I will probably not use it).
