This board is a simple carrier of Allegro’s ±12.5A ACS711 Hall effect-based linear current sensor with overcurrent fault output, which offers a low-resistance (~1.2 mΩ) current path and electrical isolation up to 100 V. This version accepts a bidirectional current input with a magnitude up to 12.5 A and outputs a proportional analog voltage centered at Vcc/2 with a typical error of ±5%. It operates from 3 V to 5.5 V, so it can interface directly to both 3.3 V and 5 V systems.
