This board is a simple carrier of Allegro’s unidirectional 30A ACS724LLCTR-30AU 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 30 A and outputs a proportional analog voltage (133 mV/A) that measures 500 mV when the input current is zero. The typical output error of ±0.7%. It operates from 4.5 V to 5.5 V and is intended for use in 5 V systems.
