The board features temperature sensor for measuring onboard temperature, current sensors for current measurement for 1.2V, 1.8V, and 3.3V AM273x supply rails, and EEPROM for storing board ID. These are connected to the AM273x EVM through the I2C bus.
Table 2-10 shows the list of I2C devices available in the AM273x EVM board and the address.
