Connecting the Boards
shows the connection of the CC3120 BoosterPack module to the CC31XXEMUBOOST board.
The connectors must be aligned carefully, because the CC31XXEMUBOOST board does not have polarity
protection, and the serial flash can be erased as a result. Pin 1 on each of the connectors is marked on
the board using a small triangle marking; these pins must be aligned while connecting.

CAUTION
Align pin 1 of the boards together using the triangle marking on the PCB. An
incorrect connection can destroy the boards permanently.
Ensure that none of the header pins are bent before connecting the two boards.
