The ACS714 Current Sensor Carrier provides a compact breakout for Allegro's ±5A ACS714 Hall effect-based linear current sensor. It offers a low-resistance (~1.2 mΩ) current path and electrical isolation up to 2.1 kV RMS, making it ideal for safely monitoring current in a wide range of applications.

This bidirectional sensor accepts current up to ±5A and outputs a proportional analogue voltage centred at 2.5V, which can be read directly by an Arduino or other microcontroller. The compact carrier board includes bypass capacitors and is ready to integrate into 5V systems.

Key Features
