AS5600 Magnetic Encoder Module (12-bit Precision)

AS5600 Magnetic Encoder Module is a contactless rotary position / angle sensor that provides accurate 0°–360° absolute angle measurement using a rotating magnet. With 12-bit precision (4096 positions per revolution), it’s ideal for robotics, motor position feedback, knobs, CNC projects, and any application that needs smooth, wear-free angle sensing. It supports I²C digital output and also provides an analog/PWM output on many module versions.

Key Features

• 12-bit resolution: 0–4095 counts per full rotation (high precision)

• Absolute angle measurement: 0°–360° (no homing needed)

• Contactless magnetic sensing: no wear, long lifetime

• I²C interface for microcontrollers (Arduino, ESP32, STM32, Raspberry Pi)

• Many modules include Analog output and/or PWM output

• Fast and smooth response suitable for real-time control

• Easy to integrate as a small breakout module

Full Specifications (Module / Sensor Typical)
