The encoder module is a rotary encoder with integral push button mounted on a small PCB with a 4-pin header and a 6-8 inch 4-pin cable . It comes fully assembled and ready to use. Use the cable to connect directly to any ePot.V3 or V4 board, or to the OLED display adapter board.
The pin header connections are labeled as follows:
- A or EA – leg A of the encoder
- B or EB – leg B of the encoder
- S or ES – encoder switch
- G – power ground
Please note that if turning the encoder clockwise decreases the volume rather than increasing it then just swap the A & B connections.
