A compact carrier board for the Allegro ACS711EX Hall effect-based linear current sensor with overcurrent fault output. It measures bidirectional current up to ±31 A with a proportional analogue voltage output centred at Vcc/2. The sensor offers a very low resistance current path (~0.6 mΩ) and electrical isolation up to 100 V.

Operating from 3 V to 5.5 V, the board interfaces directly with both 3.3 V and 5 V systems without level shifting.
