AS5600 magnetic encoder, Arduino library

AS5600 Position Sensors IoT Demo Kit

AS5600

AS5600 is a super handy magnetic rotary sensor—no physical contact needed, measuring angles from 0° to 360° precisely. It outputs via I²C or PWM, easy to connect with Arduino or STM32. You can set zero-position anywhere, making it ideal for DIY encoders, knobs, or motor position sensing projects.

AS5600 Pinout

When using the AS5600, place the magnet directly above the chip with a 2–3mm gap. Add a 100nF decoupling capacitor near VDD. For angle output, connect SCL/SDA for I²C or read directly from OUT for PWM/analog. Adjust rotation direction via the DIR pin. Leave NC pins unconnected.

AS5600 Angle Sensor Circuit Example

This AS5600 circuit is straightforward and effective. AMS1117 converts 5V to 3.3V for stable operation. Don’t forget pull-up resistors on SDA and SCL lines for reliable I²C communication. DIR pin grounded means no direction reversal by default. Place your magnet directly above the sensor, around 2-3mm away, ideal for DIY motor control, knobs, or robotic joints.

AS5600 Arduino Magnet Position Project

AS5600 with Arduino for angle sensing is straightforward—just place a magnet 2-3mm above the sensor and it instantly reads angles (0-360°). Connect VDD, GND, SDA, SCL, and Arduino gets the angle via I²C. Perfect for servo control, LED brightness adjustment, or knob interfaces. With zero contact, no wear, and high precision, it’s great for DIY robotics and interactive projects.

AS5600 I2C Wiring Guide

Connecting AS5600 via I²C is straightforward:

• VDD to Arduino/ESP32 3.3V or 5V.

• GND to ground.

• SDA and SCL to the MCU’s I²C pins (A4 and A5 for Arduino UNO).

No extra pull-up resistors needed if using Arduino boards, but add 4.7kΩ resistors if needed. DIR can stay disconnected, and OUT pin only if PWM or analog is required. Place magnet 2-3mm above the sensor, keeping it centered.

AS5600 Motor Position Feedback

The AS5600 is great for motor position feedback in low-to-medium speed and accuracy scenarios, like servos or robot joints. Just fix a magnet on your motor shaft, place it 2-3mm above the sensor, and you’ll get a real-time angle output (0-360°) via I²C. It’s frictionless, durable, compact, and easily adjustable—perfectly replacing traditional pots or mechanical encoders.
