Pololu ACS724 Current Sensor Carrier -50A to +50A

This board is a simple carrier of Allegro’s bidirectional ±50A ACS724LLCTR-50AB Hall effect-based linear current sensor, which offers a low-resistance (~1.2 mΩ) current path and electrical isolation up to 2.4 kV RMS. This version accepts a bidirectional current input with a magnitude up to 50 A and outputs a proportional analog voltage (40 mV/A) centered at 2.5 V with a typical error of ±0.8%. It operates from 4.5 V to 5.5 V and is intended for use in 5 V systems.
