MSP432P401R SimpleLink™ Microcontroller LaunchPad™ Development Kit
(MSP
‑
EXP432P401R)
2.7 BoosterPack Plug-in Module Pinout
The MSP‑EXP432P401R LaunchPad development kit adheres to the 40-pin LaunchPad development kit
pinout standard. A standard was created to aid compatibility between LaunchPad development kit and
BoosterPack plug-in module tools across the TI ecosystem.
The 40-pin standard is compatible with the 20-pin standard that is used by other LaunchPad development
kits like the MSP‑EXP430FR4133. This allows some subset of functionality of 40-pin BoosterPack plug-in
modules to be used with 20-pin LaunchPad development kits.
While most BoosterPack plug-in modules are compliant with the standard, some are not. The
MSP‑EXP432P401R LaunchPad development kit is compatible with all 20-pin and 40-pin BoosterPack
plug-in modules that are compliant with the standard. If the reseller or owner of the BoosterPack plug-in
module does not explicitly indicate compatibility with the MSP‑EXP432P401R LaunchPad development kit,
compare the schematic of the candidate BoosterPack plug-in module with the LaunchPad development kit
to ensure compatibility. Keep in mind that sometimes conflicts can be resolved by changing the
MSP432P401R device pin function configuration in software. More information about compatibility can
also be found at www.ti.com/launchpad.
Figure 11 shows the 40-pin pinout of the MSP‑EXP432P401R LaunchPad development kit.
Note that software configuration of the pin functions plays a role in compatibility. The MSP‑EXP432P401R
LaunchPad development kit side of the dashed line in Figure 11 shows all of the functions for which the
MSP432P401R device's pins can be configured. This can also be seen in the MSP432P401R data sheet.
The BoosterPack plug-in module side of the dashed line shows the standard. The MSP432P401R function
whose color matches the BoosterPack plug-in module function shows the specific software-configurable
function by which the MSP‑EXP432P401R LaunchPad development kit adheres to the standard.
