An on-board thermal IC ('''Texas Instruments TMP421''') connected to the [[Processing_system_peripherals_(BoraXpressBORAXpress)#I.C2.B2C0 | I²C0 interface]] can work as a local temperature sensor, providing the measurement of its internal temperature, but also as a remote temperature sensor, since it is connected to the XADC_DXP/XADC_DXN of the Zynq processor, providing the measurement of the Zynq internal temperature.
For a detailed description of the thermal IC characteristics, please refer to the TMP421 datasheet.
