Overview This current sensor is a carrier board or breakout board for Allegro’s ACS709LLFTR-35BB-T Hall effect-based linear current sensor with overcurrent fault output; we therefore recommend careful reading of the ACS709 datasheet (1MB pdf) before using this product. The sensor has an operating voltage of 3 V to 5.5 V and an output sensitivity of 18.5 mV/A when Vcc is 3.3 V (or 28 mV/A when Vcc is 5 V). The following list details some of the sensor’s key features:
