Current sensor boards ACS711

This board is a simple carrier of Allegro’s Âą31 A ACS711 Hall effect-based linear current sensor with overcurrent fault output, which offers a low-resistance (~0.6 mΩ) current path and electrical isolation up to 100 V.This current sensor is a carrier board or breakout board for Allegro’s ACS711KEXLT-31AB-T Hall effect-based linear current sensor with overcurrent fault output; we therefore recommend careful reading of the ACS711 datasheet (551k pdf) before using this product. This sensor has an operating voltage of 3 V to 5.5 V and an output sensitivity of 45 mV/A when Vcc is 3.3 V (or 68 mV/A when Vcc is 5 V). The following list details some of the sensor’s key features:
