Allegro's unidirectional 30A ACS724LLCTR-30AU Hall effect-based linear current sensor, which provides electrical isolation up to 2.4 kV RMS and a low-resistance (~1.2 mΩ) current path, is simply carried by this board. This version produces a proportional analog voltage (133 mV/A) that measures 500 mV when the input current is zero and can accept a unidirectional current input up to 30 A. ±0.7% is the usual output error. It is designed for use in 5 V systems and runs between 4.5 and 5.5 V. Summary Since Allegro's ACS724 Hall effect-based linear current sensors use this current sensor as a carrier board or breakout board, we advise carefully reading the ACS724 datasheet (1MB pdf) before using this product. The list that follows describes some of the
