The F280013x LaunchPad includes headers on J12 which are used for connecting a linear or rotary incremental encoder. These headers take 5 V input signals that are stepped down to 3.3 V and wired to the F2800137 MCU. These signals are connected to the eQEP modules on the device when switch S5 is set appropriately, see Table 3-5. The headers have the EQEPA, EQEPB, and EQEPI signals available for the single eQEP module as well as pins for GND and 5 V.
