Pololu Current Sensor 0A to +20A
This board is a simple carrier of Allegro’s unidirectional 20A ACS724LLCTR-20AU 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 20A and outputs a proportional analog voltage (200 mV/A) that measures 500 mV when the input current is zero. The typical output error is ±0.7%. It operates from 4.5V to 5.5V and is intended for use in 5V systems.
