I managed to get the board working but there is one thing that bothers me. Arduino is a 5V device but max VDD for FXAS21002C and FXOS8700CQ is 3.3V. So the SDA and SCL (or SCLK and MOSI) coming from arduino is 5V. I read the datasheet but there is no info about 5V tolarance. Can it damage in any way FXAS21002C or FXOS8700CQ?
