My plan is to realize a selfmade crank mounted bike powermeter.
The size of the PCB should be as small as possible, but still hand solderable.
I decided to use 0603 size smt components.
The overall cost should be as low as possible. Cost estimations will follow.
ARM CPU with ANT+ support
Amplifier and AD-Converter
LIPO 3.7V 1800mAh
to measure force

First test with the hardware has been very promising.
I was able to download the NordicSemi bikepowermeter TX example into my hardware.
After starting the firmware my powermeter connectec via ANT+ to my Garmin Forerunner 735xt and the simulated power and cadence was shown.
But now I do have problems with the software, is there someone who can help me ?
