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.....
