Current sensor carriers on one tile — twenty-one boards from Pololu, Hall-effect and TMR, from the 7.62 × 10.16 mm ACS37041 micro carrier to the 48.26 × 47.62 mm ACS37800 I²C power monitor. A drawing here is a board rather than a SKU: Pololu list ten current ratings against the one ACS724 carrier and fifteen against the CT43x, so the model picks the board and the range is a matter of which part you buy. Each declares its header row as contacts on the 0.1 inch pitch, read from the CAD, so a cable can be run to one.
