3.1.4 Encoder Connectors

The F28003x LaunchPad includes two headers, J12 and J13, which are used for connecting linear or rotary incremental encoders. These headers take 5 V input signals that are stepped down to 3.3 V and wired to the F280039C MCU. These signals are connected to the eQEP modules on the device when switch S5 is set appropriately, see Table 3-5. Each header has the EQEPA, EQEPB, and EQEPI signals available for each eQEP module (1 and 2) as well as pins for GND and 5 V.
