3.2 Board Setup With An External MCU

The CC3120 BoosterPack evaluation board requires a host MCU to execute the user application. This guide uses the MSP-EXP432P401R LaunchPad as a reference.

Figure 8 shows how the MSP-EXP432P401R LaunchPad jumpers must be configured.

Figure 9 shows how to mount the CC3120BOOST board on top of the MSP-EXP432P401R board. Ensure P1.1 of both boards are aligned with each other, as indicated by the white arrows on both boards. The micro USB connector on the MSP-EXP432P401R board is used as the power source and also as the programming interface for the user application.
