Interrupts on the flora lsm303 accelerometer

Post by ishkhanna »

Hello,

I bought a flora accelerometer (lsm303) and didn't really pay attention to the fact that this breakout doesn't have the interrupt pinouts.
Since this is a wearable project I would like to use the flora version, but I also would like to use the interrupts so I am able to put the flora to sleep while there is no movement detected and then wake the flora up using the interrupts from the accelerometer. The goal is mainly to save battery.

Is there a way I could accomplish this goal with this product?

Best regards.

If you are skilled with a soldering iron, it is possible to solder thin wires directly to the unconnected INT1 and/or INT2 pins on the chip.

The regular breakout is a little larger, but includes breakout holes for the interrupts.
