🚀 Why It’s Ideal for Your Projects

• High range & flexible usage: With a 20 A measurement capacity, you can monitor motors, power supplies, battery systems, and more — all within a compact module.

• Simple to integrate: The output is a standard analog voltage proportional to current flow, making it easy to interface with boards like Arduino, Raspberry Pi (via ADC), and similar microcontrollers.

• Precision design: Includes features like low-noise analog signal path, fast 5 µs rise time for current steps, and isolation between sensor and microcontroller.
