through ST25DV to communicate with I2C Sensor

[FZhao]

Hi,

I am thinking if it is possible to connect a low power I2C sensor to ST25DC, and use a reader to read out the values through the ST25DV(Powered by the Veh from ST25DC), or do I need extra MCU between the ST25DV and the I2C sensor to done the communication?

​Hello,

The ST25DV-I2C is I2C slave device only. In order to read data in your sensors, you need a master device, so you will need to add an MCU. The MCU will be I2C master for both sensors and ST25DV.

Best regards,
