ACS711EX Current Sensor Carrier -31A to +31A

This board serves as a straightforward carrier for Allegro's ±31 A ACS711 Hall effect-based linear current sensor featuring overcurrent fault output. It provides a low-resistance (around 0.6 mΩ) current path and electrical isolation up to 100 V. The bidirectional current input can handle magnitudes up to 31 A, outputting a proportional analog voltage centered at Vcc/2 with a typical error of just ±4%. Operating from 3 V to 5.5 V, it can directly interface with both 3.3 V and 5 V systems.

Using this current sensor carrier is easy. First, connect it to your circuit following the standard wiring methods. Make sure the power supply voltage is within the 3 V to 5.5 V range. When using, don't exceed the maximum current of 31 A to avoid damage. Regarding maintenance, keep it in a dry and clean environment. If there's dust on the board, use a soft brush to gently clean it. Also, check the connections regularly to ensure they are secure. If you notice any abnormal output or performance issues, check the power supply and connections first.
