The LaunchPad kit adheres to the 20-pin LaunchPad pinout standard. A standard was created to aid compatibility between LaunchPad kits and BoosterPack modules across the TI ecosystem.
While most BoosterPack modules are compliant with the standard, some are not. The MSP-EXP430FR2433 LaunchPad kit is compatible with all 20-pin BoosterPack modules that are compliant with the standard. If the reseller or owner of the BoosterPack module does not explicitly indicate compatibility with the MSP-EXP430FR2433 LaunchPad development kit, compare the schematic of the candidate BoosterPack module with the LaunchPad kit to ensure compatibility. Keep in mind that sometimes conflicts can be resolved by changing the MSP430FR2433 device pin function configuration in software.
To check the compatibility of your desired BoosterPack modules for your design, with a LaunchPad kit of your choice, you can use the BoosterPack Checker tool. This allows you to select any LaunchPad kit that TI offers and determine its compatibility with any number of BoosterPack modules. You can also add your own BoosterPack module to check its compatibility as you prototype that next design.
Figure 11 shows the 20-pin pinout of the MSP430FR2433 LaunchPad development kit.
The inner side of the dashed line shows some of the software selectable functions on each pin, including the functions that conform to the standard. However, each pin may have other functionalities that can be configured by the software. See the MSP430FR2433 data sheet for more details on individual pin functions.
