Partslist of the used components
- Remark: Some of the components used here seem to be very strange because they may be not available anymore on the market. The reason why I have used those components is very simple - I have just found them in my stock. Please feel free to use other components....
- The following components are used on my "prototype":
| Count | Part | Cost | e.g. available at... | Remark |
|---|---|---|---|---|
| 1 | Odroid-N2 | 80,- Euro | Pollin: Odroid-N2 | |
| 1 | 16GB eMMC Module N2 Linux | 23,- Euro | Pollin: ODROID-N2 eMMC Modul, 16GB, mit Linux | |
| 1 | Odroid Backup Battery | 4,- Euro | Pollin: ODROID BACKUP BATTERY | |
| 1 | Odroid-N2 VESA Mount-Kit | 4,25 Euro | Pollin: ODROID-N2 VESA-Mount-Kit | By using the Odroid-N2 mount kit it is possible to mount it on such an adapter 
|
| 1 | Joy-IT LCD10 | 140,-Euro | was cheaper in the past |

Used Power-Supply
- I've found a desktop-power supply which was originaI used for an external 5 1/4 inch hard-drive. It provides 12V / 2A and 5V / 2A thus exactly what is neede for the piano expander.
- 5V / 2A for the Joy-It Touch-Display
- 12V / 2A for the Odroid-N2
- The connector which was used on this power-supply was a Mini-DIN4 Power Plug (PP).

mounting VESA-Adapter onto the Piano-Expander
- as you can see on the picture below the Odroid-N2 has 4 holes on its heatsink for mounting the optional Odroid-N2-Vesa-Mount-Kit.
- Don't waste money while buying the old Odroid-N2 VESA bracket. This Bracket is not compatible with the VESA mounting hole dimensions (neighter 100x100mm nor 75mm x 75mm).
- The solution for me was "just mounting the VESA-Adapter for a microphone-stand directly onto the Odroid-N2 heatsink"
- I screwed 4x 12mm M3 standoffs into the heatsink.....
- ....and mounted the removable part of the VESA-Microphone-Stand-Adapter directly onto the ODROID-N2 heatsink
- VESA-Adapter: the "microphone-stand-part"

- remark: the screws to hold the 2 parts of the housing together are not there
