AS5600 Magnetic Encoder Module V2

Track precise rotational position without any physical contact using the AS5600 Magnetic Encoder Module V2. Built around the AS5600 contactless Hall-effect sensor from ams-OSRAM, this module reads the angular position of a diametrically magnetized magnet placed just above the chip, delivering a full 360° reading with 4096 discrete steps per revolution. Unlike mechanical potentiometers or incremental encoders, it always knows the absolute shaft angle instantly, even right after power-up, with no homing or calibration routine required.

The module offers flexible output options, including I2C for direct microcontroller communication, along with PWM and analog voltage modes for simpler wiring setups. It ships on a compact breakout board with a standard 4-pin connector, ready to pair with Arduino, ESP32, or Raspberry Pi projects. This makes it an excellent choice for hobbyists and engineers building brushless motor controllers, robotic joints, camera gimbals, DIY servo feedback systems, or contactless rotary knobs. Its smart low-power mode also helps conserve energy in battery-driven designs.

A magnet is typically included, and the sensor works reliably at a mounting distance of 0.5mm to 3mm above the magnet, making installation straightforward even in tight enclosures.
