Grove - Step Counter(BMA456) The Grove - Step Counter(BMA456) is based on BMA456, which is an exetremely small, triaxial, low-g high performance accelerations module. Thanks to the special algorithm of BOSCH, we made this module a portable pedometer. Relaiable, cost-effective, on top of that, it s very easy to use, you can easily add this plug and play module on your wearable devices.
