ACS724 Current Sensor Carrier -20A to +20A
This board is a simple carrier of Allegro’s bidirectional ±20A ACS724LLCTR-20AB 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 20 A and outputs a proportional analog voltage (100 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.
