2 BoosterPack Functional Interface
The Tiva C Series LaunchPad BoosterPack Interface provides compatibility with the original MSP430
LaunchPad BoosterPack interface. This interface consists of the outer 10-pin headers. The pins are
spaced 0.10 in (2,54 mm) apart with the two headers located 1.8 in (4,572 cm) apart.
Table 2 and Table 3 both provide information about which Tiva C Series MCU peripherals are routed to
each of the interface pins. The J1 connector is located on the far left side of the Tiva C Series LaunchPad.
The J2 connector is located on the far right side of the TM4C123G LaunchPad. Software is used to
configure the TM4C123GH6PM pin for one of the functions found in the tables. Highlighted functions
indicate configuration for compatibility with the MSP430 LaunchPad.
