4.2 EVM Operating Conditions

The HDC2022EVM power is supplied via the USB connector. The LDO (U4) converts the 5V from the USB to 3.3V used by the HDC2022 and the MSP430. The EVM may be directly inserted into a USB port on a PC or laptop, or may be connected to the latter using the appropriate USB cable.

The controller and device sides of the EVM have different temeperature limits as shown in Table 2. These are set by the onboard MSP430F5528 and the HDC2022 ICs on the controller and breakout portions respectively.
