1 Introduction
The Texas Instruments HDC3020 Evaluation Module (HDC3020EVM) enables designers to evaluate the
operation and performance of the HDC3020 Relative Humidity and Temperature Sensor. The EVM hosts an
MSP430F5528 microcontroller (MCU) as well as the HDC3020. The MCU is used to control the HDC3020
and communicate with a host PC through a USB port. The EVM is designed to be broken into two sections,
if desired. The sensor section can be separated from the MCU section of the board to reduce thermal mass
surrounding the HDC3020. The HDC3020EVM is configured by default to use the HDC3020 device with I
