I would like to build a LiPo battery powered sensor using the Onion Omega2+
I am considering mounting the Onion Omega2+ onto the I2C shield with ethernet port (I2C Shield for Onion Omega with Ethernet Port).
With this shield I would like to connect to I2C sensors.
A sensor that I am particularly interested in is the 89BSD pressure sensor (http://www.strainsense.co.uk/products/pressure-sensor-digital-sp1-i2c-output/89bsd).
The sensor’s datasheet says that the interface type is I2C and the voltage range is 1.8V to 3.6V.
I am not sure when NCD refers to their 5V I2C’s, whether it means that the I2C interface can accept up to a maximum of 5V, or if the I2C interface works with 5V only.
Will the Onion I2C shield’s voltage (5V) be compatible with the 89BSD sensor I2C voltage?
