Power

The LP-EM-CC35X1 is designed to accept power from a connected LP-XDS110 and an external USB-C power connection together.

WARNING: To verify the proper functioning of the board, the LP-XDS110 and USB-C power cable from the LP-EM-CC35X1 must be connected to the same computer. Do not connect the USB-C cable to a wall outlet or a different computer.

The use of Schottky diodes makes sure that load sharing occurs between the USB connectors on the LaunchPad kit and the BoosterPack module without any board modifications. The jumpers labeled J14 (1.8V) and J13 (3.3V) can be used to measure the total current consumption of the board from the onboard LDO.
