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 I2C address 0x44 (7 bit).

The EVM contains one HDC3020 (see Table 1-1)
