2.1.2. AIR BoosterPack with Stellaris LaunchPad
The following steps need to be performed on each LaunchPad/BoosterPack:
1) Remove the provided MSP430 device on the BoosterPack.
2) Install the AIR BoosterPack onto the LaunchPad board. Ensure the BoosterPack is
oriented correctly. J1 of the BoosterPack must connect to J1 of the LaunchPad. The
same is true for J2.

Optional:
The default BoosterPack configuration utilizes a software I
2
C controller (i.e. bit-banged) to
maintain compatibility with both LaunchPad types (i.e. MSP430 and Stellaris). Since the
Stellaris microcontroller supports using UART, SPI, and I
2
C at the same time (compared to the
MSP430G2553 which only has two USCIs), the BoosterPack may be configured to use the
hardware I
2
C controller instead of the bit-banged controller. The following steps need to be
performed on each LaunchPad/BoosterPack:
1) Install 10-pin connector (not included) at BoosterPack J1 Test Points location. This
corresponds to the LaunchPad J3 connector (see Figure 7). The same can be done for
BoosterPack J2 Test Points (LaunchPad J4), although this is optional. Only LaunchPad
pins J3.3 and J3.4 are utilized by the BoosterPack. The remaining J3 and J4
LaunchPad signals are simply pass-thru.
2) Remove R9 and R10 from the LaunchPad. See Figure 8 for the location of these
resistors.
