* * HARDWARE OVERVIEW * *

The uCom board, as the uTerm VT100 board, has a "transparent" USB-serial adapter connector, so you can upload firmware to the Z80-MBC2 (using Arduino IDE) or load an Intel-Hex file (with iLoad) or use XMODEM to exchange files with a PC (running a terminal emulator that supports XMODEM file transfer) while the uCom is in use.

Both the "mixed" power supply scenarios (USB-serial adapter not powered from USB but Z80-MBC2 powered and vice-versa) are managed by the HW, so you don't need to worry about it.

THE AUX_P CONNECTOR (J2)

This connector is intended for a better power supply connection for the Z80-MBC2. The use of this connector is recommended only if the uCom and the Z80-MBC2 are connected with a cable. If they are directly connected (vertically or horizontally) the use of J2 is optional:

THE "TRANSPARENT" SER_USB PORT (J4)

The uCom has a "transparent" USB-serial adapter connector, so you can upload firmware to the Z80-MBC2 (using Arduino IDE) or load an Intel-Hex file (with iLoad) or use XMODEM to exchange files with a PC (running a terminal emulator that supports XMODEM file transfer) while the uCom is in use. Both the "mixed" power supply scenarios (USB-serial adapter not powered from USB but Z80-MBC2 powered and vice-versa) are managed by the HW, so you don't need to worry about it.

CUSTOM 3D PRINTED ANGLED BRACKETS

For a solid vertical mounting two 3D printed angled brackets have been created:

The 3D .STL files are the same used for the uTerm, so you can find them there (in the File section).

CUSTOM 3D PRINTED STRAIGHT BRACKETS

For a solid horizontal mounting two 3D printed straight brackets have been created:

The 3D .STL files are the same used for the uTerm, so you can find them there (in the File section).

* * HOW TO GET A PCB * *

I've prepared an "easy link" to order a small lot (min. 5 pcs) of PCB here.

* * HOW TO GET A KIT OR AN ASSEMBLED UNIT * *

If you are looking for a kit with all the needed parts (including the 3D printed parts) or an assembled unit ready to use there is a professional seller that can sell both and ship worldwide.

The link to the seller is this one.
