Pololu Current Sensor -2.5A to +2.5A

This board is a simple carrier of Allegro’s bidirectional ±2.5A ACS724LLCTR-2P5AB 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 2.5A and outputs a proportional analog voltage (800 mV/A) centered at 2.5V with a typical error of ±1.5%. It operates from 4.5V to 5.5V and is intended for use in 5V systems.
