ONE Accelerometer Orientation

I received mine just a day ago, W00t!

For the LSM303 accelerometer, which direction is “forward”? Looking at the spec sheet for it that forward would be the narrow edge opposite the USB connector…


Correction: The correct spec sheet for the LSM303 on our ONE boards looks more like a LSM303DTR (LGA-16, not LGA-14).

The orientation of this chip is similar to the other, placing X facing the short edge with the LoRa antenna, and Y towards the long edge with pins for D2-D11.

Based on the datasheet, believe these are the axes:

X+ -> USB connector
Y+ -> Short side of the board away from the GPS antenna
Z+ -> Top of the board upwards
