Looks like the ADXL345 is nice and it has FF free fall detection. I am a bit troubled with activating it, but I am sure it will work in the end. thx a lot!
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
I don't I'm afraid... I imagine you want a low power one that has a programmable IRQ line on it (eg, that can be programmed to detect freefall).
