I2C Interface: The MS5637 Grove compliant module can interface to the host in I2C model with 5V supply, it has a Grove compatible four pins port connector configured for I2C.
External Control Signals 5V supply: The IC operates as an I2C slave using the standard 2-wire I2C connection scheme. As IC is power rated at 3.6V, the board integrates necessary fixture such as a regulator and electrical level shift so that the SCL and SDA signals could be driven directly from an external 5V I2C lines and power supply.
