SparkFun ACS723 Current Sensor Breakout - 5A AC/DC Hall Effect, 400mV/A Sensitivity
The SparkFun ACS723 Current Sensor Breakout is a Hall effect-based module for measuring AC and DC currents up to 5A, featuring a 400mV/A base sensitivity and electrical isolation for safe integration with 5V microcontrollers like Arduino and Raspberry Pi.
Features
- Measures AC and DC currents from 10mA up to 5A with a base sensitivity of 400mV/A.
- Utilizes Hall effect sensing for full electrical isolation between the measured circuit and the sensing circuit.
- Analog output bandwidth is user-selectable via Jumper, from a default 20kHz (low noise) up to 80kHz.
- Operates from a single 5V DC supply, compatible with common development boards.
- Compact breakout board format simplifies prototyping and integration.

The SparkFun ACS723 Current Sensor Breakout is engineered around the Allegro MicroSystems ACS723 Hall effect current sensor IC. This design provides a voltage output linearly proportional to the current flowing through the onboard current-carrying path (IP+ and IP- pins). The Hall effect principle ensures complete galvanic isolation, allowing you to safely monitor high-side or low-side currents in circuits operating at different voltage levels than your microcontroller.
The module includes a configurable low-pass filter on its output. By default, the bandwidth is set to 20kHz to minimize noise at higher gain settings, optimizing for typical embedded applications. For full-frequency response, the onboard JP1 Jumper can be closed to enable the sensor’s native 80kHz bandwidth. This breakout is ideal for power monitoring, inrush current detection, and overload protection in DIY electronics and prototypes.
