2.1.6.1 BoosterPack Plug-in Module Interface 1

The Ethernet LaunchPad development kit features two fully independent BoosterPack XL connectors. BoosterPack Plug-in Module Interface 1, located near the XDS110 emulator, is fully compliant with the BoosterPack plug-in module standard.

I2C is provided in both the original BoosterPack plug-in module standard configuration as well as the updated standard location. Use of I2C on the bottom left of the BoosterPack plug-in module connections per the updated standard is highly encouraged whenever possible.

Motion control advanced PWM connections are provided on the inner right connector for motion control applications.

Table 2 lists the BoosterPack plug-in module pins and the GPIO alternate functions available on each pin. The MSP432E401Y GPIO register GPIOPCTL values are shown for each configuration. The headers in this table are labeled from left to right in ten pin columns. J1 and J2 make up the outer BoosterPack plug-in module standard pins, and J3 and J4 make up the inner BoosterPack XL standard pins.
