2.5.3 I C Connections
The board features an accelerometer and a temperature sensor for the out-of-box demo. These are

By removing J15 and J16, the accelerometer and the temperature sensors are isolated from the I
This measure also removes the I
connection to the circuit requires the user to install external pullup resistors.
