2.1.7.1 BoosterPack Sites

The F28004x LaunchPad features two fully independent BoosterPack XL connectors. BoosterPack site #1, located above the F28004x MCU and below the XDS110 debugger, is compliant with the BoosterPack standard with a few exceptions as noted in Figure 3. BoosterPack site #2, located under the F28004x MCU, is compliant with the BoosterPack standard with a few exceptions as well, noted in Figure 3. 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 onboard switches or adding or removing 0 Ω resistors. This is described in Section 2.3.

The GPIO pin number as well as the BoosterPack compliant features are listed in Figure 3. Each GPIO has multiple functions available through the GPIO mux. A few special functions have also been listed above; the full GPIO mux table can be found in theTMS320F28004x Piccolo microcontrollers data sheet.
