Description
AS5600 I2C Magnetic Encoder Module
Introduction
The AS5600 magnetic encoder measures absolute shaft angle across 0–360° using an on-axis diametric magnet. It combines 12-bit resolution with I²C readout and a selectable analog or PWM output, operates from 3.3–5 V, and supports zero-point, range, and direction configuration for quick integration into knobs, servos, and general rotary sensing.
Key Features
-
12-bit absolute angle: precise 0–360° measurement.
-
Dual output options: ratiometric analog or PWM, in addition to I²C registers.
-
3.3–5 V operation: flexible supply for common MCU rails.
-
Programmable zero/range: map full scale to a custom mechanical span.
-
Direction selection: hardware pin to choose CW/CCW polarity.
-
Contactless sensing: no mechanical wear; smooth, high-repeatability feedback.

Compatibility & Tips
-
Use a diametric magnet centered on the shaft; keep a small, consistent air gap.
-
Add I²C pull-ups and a 0.1 µF decoupling capacitor near VDD.
-
Program zero and maximum angles to match your mechanical travel.
