The CB4XV1 evaluation board simplifies sensor evaluation and prototyping for Sensirion SHT40, SGP40, and STMicroelectronics LPS22DF. Compatible with the STMicroelectronics DIL 24 slot, it is powered by the STEVAL-MKI109V3 motherboard and STM32Nucleo board. The sensor combination on this board supports the evaluation of prototypes requiring relative humidity, temperature, volatile organic compounds, and atmospheric pressure. This device can serve as a platform for evaluating single sensors and for prototyping using one or more sensors.
