2.1.1.5 BoosterPack Sites

The F28E12x LaunchPad features a BoosterPack connector. BoosterPack site 1 is compliant with the BoosterPack standard. 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 and removing 0Ω resistors. This is described in Section 2.1.3.

The GPIO pin numbers as well as the BoosterPack compliant features can be viewed in the LAUNCHXL-F28E12X Pinout Map. Each GPIO has multiple functions available through the F28E12x device's GPIO mux. Some specific functions have been listed in the Pinout Map; the full GPIO mux table can be found in the F28E12x Real-Time Microcontrollers data sheet.

All of the analog signals (denoted ADCIN) of the F28E12x MCU are routed to the J1/J3 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 populate these components with specific values to filter out noise arriving at the device ADC input.
