2.2.9 BoosterPack Overview

This reference design also integrates BoosterPack™ headers which offer several advantages to designers. By mounting an MCU LaunchPad to the TIDA-010932 board, several important device outputs can be monitored by the host MCU, and in the case of a wireless MCU, can also relay this data to a gateway device.

Pins 6 and 8 on J7 in Figure 2-13 are tied to the output of the INA2180, which with an MCU attached and powered via the TIDA-010932 board, can characterize a more complete system current consumption. More BoosterPack™ Plug-in Modules can be added as well to allow for a complete systems estimate for power consumption.
