2.6 On-Board Sensors

The AWR2E44PEVM provides access to an on-board temperature sensor (TMP112AIDRLR) and four on-board current sensors (INA228AIDGST). These sensors can be controlled by the radar via I2C. For details about the I2C addresses of these sensors, refer to Section 2.9.3.

The current sensors are designed to measure the current being supplied to the various power rails of the AWR2E44P device. For details on the supply nodes that can be measured using the current sensors, refer to Table 2-7.
