– 32 bit, single channel quadrature encoder counter, inputs: A, B, and Index.
– SPI interface for fast serial transfer of the encoder count.
– Works on 5V supply.
– Jumper to connect on board pull up resistors, which make it suitable for higher cost optical encoders, like the Avago HEDL as well as low cost ones.
– IDC connector and header pins available for mounting different types of optical encoders.

– Connectors for HEDS and HEDL encoders.

– Screw terminal for low cost encoders.

– Through hole components are not soldered (but provided), you have to solder it yourself.
