ACS724 Current Sensor Carrier 0A to 10A Stepper Motor Drivers it can achieve high-sensitivity sensingThis 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 m) 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
