 Assembly Instructions Parts Needed: (6) M2x13mm screws (4) M2x25mm screws (3) M4x22mm bolts (1) M4x32mm bolt (4) 4mm lock nuts Begin by installing the PCB bracket into the rear of the faceplate. This can be glued onto place (although the PCB mounting screws will hold it in place).
  • Page 6 Assemble and solder all of the components onto both the 
 faceplate and Mobiflight control board. Place the button onto the key switches. The buttons will sit loosely on to of the switches but will stay in place once the faceplate is in place.
  • Page 7 Place the faceplate assembly onto the assembled PCB. 
 Carefully make sure all the buttons slide into the holes in the faceplate Attach the PCB to the faceplate using (6) M2 x 13mm screws. Make sure to leave the holes circled in red empty.
  • Page 8 Now we can install the Mobiflight control board with the 
 bracket and (4) M2 x 25mm screws. Install the Arduino card onto the back of the Mobiflight control board.
  • Page 9 Attach the dual encoder knobs and the range pan knob. N
 Install the unit into the cutout in your instrument panel and insert (3) M4 x 22mm and (1) M4 x 32mm bolts. (Note that these are minimum lengths. If your panel is thicker than 1/8 inch then you’ll need longer bolts).
  • Page 10 Install the rear panel mount bracket and (4) M4 lock nuts. Complete… Now you can plug the Arduino into your pc via usb and plug you 12v power supply into the backlight power connector. Follow the Mobiflight instructions on the website for installation of the Mobiflight configuration.
