The F280013x LaunchPad features two fully independent BoosterPack XL connectors. Both BoosterPack sites 1 and 2 are compliant with the BoosterPack standard, however many pins are left unconnected to the F280013x device because of the low pin-count. To expand the functions available to the user on this LaunchPad, some signals are also routed to alternate locations on the board. These alternate routes can be selected by manipulating the on-board switches or by adding or removing 0-ohm resistors. This is described in Section 3.3.

The GPIO pin numbers as well as the BoosterPack compliant features can be viewed in the LAUNCHXL-F2800137 Pin Mapping (SPRUJ33). Each GPIO has multiple functions available through the F280013x device's GPIO mux. Some specific functions have been listed in the Pin Mapping document; the full GPIO mux table can be found in TMS320F280013x Real-Time Microcontrollers.

All of the analog signals (denoted ADCIN) of the F280013x MCU are routed to the J1/J3 and J5/J7 BoosterPack headers on the left side of the board. Close to the respective BoosterPack header, each ADC input signal has component pads for a series resistor and parallel capacitor to create an RC filter. By default, a 0-ohm resistor is populated and the capacitor is left unpopulated. Users can wish to populate these components with specific values to filter out noise arriving at the device ADC input.
