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
- ±5A Bidirectional Range – Measures current flowing in both directions
- 185 mV/A Sensitivity – Proportional analogue output centred at 2.5V
- High Isolation – Electrical isolation up to 2.1 kV RMS
- Low Resistance – ~1.2 mΩ current path for minimal circuit impact

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- RMS
- RMS is a way of describing the effective level of an AC signal, such as an audio output voltage. It helps compare audio output levels more meaningfully than a peak voltage number.
