SG53 MODULE FOR SPINDLE
The SG53 module is designed to enable easy integration of power sensor features to build into a bike crank axle/spindle power meter. Only a rechargeable Lithium battery and a set of strain gauges (both provided) are required to make a bike power sensor product.
A micro-USB connector is used to charge the attached Lithium battery. Several different battery styles are compatible with the SG53 modules including 14550, 14430, 14250 with capacities from 250mAh to over 650mAh.
The SG53 module series is based on a chip/module, which has been certified to comply with radio regulations or standards covering major markets include North America, Europe, Australia, New Zealand, and Japan. The chip/module has also been qualified by the BLUETOOTH SIG. This allows fast track certification of the final power meter product.
The physical dimensions of 10x30x6mm make integration into a spindle feasible.
