This board is a simple carrier of Allegro’s unidirectional 10A ACS724LLCTR-10AU 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 unidirectional current input up to 10 A and outputs a proportional analog voltage (400 mV/A) that measures 500 mV when the input current is zero. The typical output error is ±1.5%. It operates from 4.5 V to 5.5 V and is intended for use in 5 V systems.
