AS5600 Magnetic Encoder 12-Bit Precision Angle Sensor Module

The AS5600 Magnetic Encoder 12-Bit Precision Angle Measurement Sensor Module is a compact, high-resolution contactless position sensor designed for robotics, motor control, automation projects, and DIY electronics. Built around the AS5600 IC, it delivers 12-bit angular resolution — that's 4096 discrete positions per full rotation — making it an excellent choice for makers, engineers, and hobbyists who demand accuracy and repeatability.

With its tiny footprint of just 2.5 × 2.5 × 0.4 cm (0.98 × 0.98 × 0.16 in), this sensor module fits seamlessly into tight enclosures and compact builds. Communication is handled via the standard I²C interface, making it plug-and-play compatible with popular microcontrollers such as Arduino, ESP32, STM32, and Raspberry Pi.

Frequently Asked Questions

Q: What is the AS5600 Magnetic Encoder Sensor Module and how does it measure angle?

A: The AS5600 is a contactless magnetic rotary position sensor that uses a small diametrically magnetized magnet placed above the chip. As the magnet rotates, the AS5600 detects the changing magnetic field and converts it into a precise 12-bit digital angle value (0–4095) via the I²C interface, representing a full 360° rotation with no physical contact or wear.

Q: Which microcontrollers are compatible with the AS5600 Magnetic Encoder Module?

A: The AS5600 module communicates over standard I²C, making it compatible with virtually any microcontroller that supports I²C — including Arduino Uno/Nano/Mega, ESP32, ESP8266, STM32, Raspberry Pi, and many more. It operates at 3.3V or 5V logic levels, covering both 3.3V and 5V systems.

Q: Do I need a specific magnet to use the AS5600 Angle Sensor?

A: Yes — the AS5600 requires a small diametrically magnetized disc or ring magnet placed concentrically above the sensor chip. The module includes a magnet strength indicator that confirms optimal positioning. Many sellers offer compatible magnets separately; check for 6mm diameter diametric magnets commonly used with this sensor.

Q: What output modes does the AS5600 Sensor support?

A: The AS5600 supports two main output modes: I²C digital output (providing raw 12-bit angle data) and an analog ratiometric output (proportional voltage corresponding to angular position). This flexibility makes it easy to integrate into both digital microcontroller projects and analog signal chains.
