2.9.3 I2C Connections

The board features temperature sensor for measuring onboard temperature, current sensors for current measurement for 1.2V, 1.8V, 3.3V, 1V0_RF1, and 1V0_RF2 AWR2E44P supply rails and EEPROM for storing board ID. These are connected to the AWR2E44PEVM through I2C bus.

Table 2-11 shows the list of I2C devices available in AWR2E44PEVM board and the address.
