Encoder rev 5.0 is here!
Jon Crick has updated the Encoder design and added USB support on board. The new Encoder is the same size and the connectors are in the same location as the rev 4.0 Encoder. Functionally the Encoder is the same and you have on board jumper options that allow you to select what mode of operation you would like to use.

The helicopter support includes 4 flight modes or flight conditions that are available when you enable the helicopter option. The flight modes are:
Encoder rev 4.0
This paper will introduce the Encoder electronics from the hardware design standpoint. I will reference the component designators on the schematic and I assume you have a hardcopy of the schematic for reference.
Adjusting the joystick pots with an ohmmeter
The MicroStar Encoder joystick pots can be adjusted and centered using an ohmmeter. This procedure will allow you to set all of the pot positions as you assemble the system. Here is the procedure:
