in Module
4.2
BoosterPack Pinout
The BOOSTXL-CAPKEYPAD is compatible with the 40-pin BoosterPack plug-in module standard. The
BoosterPack plug-in module headers provide I

C connectivity to a host LaunchPad development kit (SDA
and SCL signals), as well as an open-drain type interrupt request (IRQ) signal, which can be connected to
one of two BoosterPack plug-in module pins to alert a host LaunchPad development kit when new data is
available from the keypad.
