2.7 On-Board Sensors

The AWR2944EVM provides access to an on-board temperature sensor (TMP112AIDRLR) and four on-board current sensors (INA226AIDGSR). These sensors can be controlled by the radar via I2C. For details about the I2C addresses of these sensors, refer to Section 2.10.3.

The current sensors are designed to measure the current being supplied to the various power rails of the AWR2944 device. For details on the supply nodes that can be measured using the current sensors, refer to Table 2-10.
