Step 1: Mounting Adapterboard & Cubieboard
Parts required:
- 4 x long M3 screws
- 4 x plastic spacers
- Adapterboard with Cubieboard
- 4 x M3 distance bolts
Please note: Using threadlocking adhesive is not necessary. If you wannt to apply threadlocking adhesive, please use only low-strength versions like Loctite 221. Otherwise, disassembling is hardly possible!


Step 1.1: Mounting Adapterboard & Cubieboard
Note: Please have a look at Part 6: In this step you should already attache the cable shielding (black wire) of the display cable.
Mount the Adapterboard to the Cubieboard like shown in the picture. Be cautious when you need to readjust the distance between Adapterboard (green) and Cubieboard (black). Only apply force in the area of the pinheaders, so that you don´t bend the thin Cubieboard too much.
Step 1.2: Mounting Adapterboard & Cubieboard
There are 2 mounting holes on each side. For all screws we recommend to use bolt adhesive.


Step 2.1: Serial cable between Adapterboard & Cubieboard
Please note: Steps 2.1 – 2.3 can be skipped. Serial cables are not included in the kit any more on grounds of simpflification.
Parts required:
- Adapterboard & Cubieboard
- 2 pin serial cable
Now you can attache the 2 pin serial cable between the Adapterboard & Cubieboard.
The Cubieboard has a pinheader with 4 pins, but we only use the RX and TX pin. Attache the cable to the RX and TX pin.
If you don´t install the serial cable, you still have 3 serial ports on the OpenVario for external devices. And at the moment, ttyS0 (UART 1) is only configured for debugging purpose.
