AS5600 High-Resolution Magnetic Rotary Encoder Module

A mechanical rotary encoder or potentiometer wears with every rotation - brushes degrade, contacts get noisy over thousands of cycles. The AS5600 sidesteps that entirely by reading angle magnetically: a small magnet mounted on a rotating shaft, read contactlessly by the Hall-effect sensor below it, so there is no physical wear mechanism at all regardless of how many rotations the shaft sees.

12-bit resolution gives 4096 distinct positions per full rotation, precise enough for real closed-loop motor control rather than coarse position estimation, and three simultaneous output modes - I2C, PWM and analog voltage - mean the same board integrates with whatever interface a project's controller already expects, without needing a specific breakout for each.

Common uses are brushless motor position feedback in gimbals and robotics, contactless knob and dial inputs that need to survive years of use, and any application where a standard potentiometer's mechanical wear over time is a real reliability concern.
