The EVM contains one HDC1050 (See Table Table 1.

  • Page 3: Input/Output Connector Description

    This connector is used for communications with the PC and provides power for the EVM. Hardware Setup The HDC1050EVM power is supplied via the USB connector. The LDO (U4) converts the 5V from the USB to 3.3V used by the HDC1050 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.
