AS5600 Magnetic Encoder Angle Measurement Sensor Module
= 12Bit HighPrecision Non-Contact Magnetic Position Sensor =
The AS5600 is a programmable 12bit highresolution magnetic rotary position sensor that provides non-contact absolute angle measurement . It detects the position of a diametrically magnetized magnet placed above the IC, offering a reliable alternative to traditional potentiometers and optical encoders.
12Bit Resolution 4096 positions per revolution for high-precision angle tracking
Contactless Measurement - No mechanical wear for excellent durability and reliability
Operating voltage: 3.3V or 5V with I2C address 0x36
Keep magnet within 0.5mm to 3mm vertical distance for optimal detection
Ensure magnet is properly aligned with the sensor center and is sufficiently strong

= Connection Guide =
Basic I2C wiring to Arduino:
- VIN: 5V (or 3.3V) power
- GND: Ground
- SDA: I2C data line
- SCL: I2C clock line
- OUT: Optional analog/PWM output
Use I2C address 0x36 by default not userconfigurable
For analog output, connect OUT pin to ADC input 0V to VDD corresponds to 0360°
DIR pin must be tied to GND or VDD - leave floating causes erratic behavior
I2C lines require pull-up resistors (10kΩ onboard on many modules)
= Troubleshooting =
No angle data:
- Verify magnet is detected and within correct field range
- Check I2C connections and pull-up resistors
- Ensure DIR pin is properly tied (GND or VDD)
Inaccurate readings:
- Align magnet with sensor center, vertical distance 0.5-3mm
- Use a rare earth magnet (e.g., neodymium) for reliable field strength
- Check magnet is diametrically magnetized, not axially
