I'm tinkering with an electronic skateboard build and I'm looking for a way to do some current measurements "on-the-go". What's the easiest way to implement this?
It wouldn't be a part of the final design, I'm just trying to collect real-world power data for my second board revision.
Basically, I'm looking for something like this DIY power meter/logger (pictured below) but for higher currents (up to ~20A to be safe).
Would something like SparkFun's split core current transformer (pictured below) combined with a battery powered Arduino work?
