Absolute Encoders

We're Updating our Documentation! For the most up-to-date information about the SPARK MAX and other ION Motor Controllers please check out the following new documentation pages:
The SPARK MAX does not need to be configured to a specific mode to accept input from an absolute encoder as long as the encoder is connected to the SPARK MAX Data Port.

Connecting an Absolute Encoder

Connecting an absolute encoder that is not a Through Bore Encoder will likely require a custom wiring harness or SPARK MAX Data Port Breakout Board to connect the necessary encoder power, ground, and signals to the SPARK MAX Data Port. When using an Absolute Encoder use the following pinout information for the Data Port:
