Position sensor AS5600 breakout

The Soldered AS5600 Position Sensor Breakout measures rotation without ever touching the thing that's turning. Built around the AMS AS5600, a 12-bit contactless magnetic angle sensor, it reads the absolute position of a small diametrically magnetized magnet spinning above the chip and reports it as a full 0-360° angle with 4096 steps per turn - a true "contactless potentiometer".
That makes it a great fit for endless-rotation knobs, motor and joystick feedback, robot joints, pedals, or RC-style servos. You can read the angle over I2C - plug straight in with the two Qwiic connectors, or use the 4-pin header if your microcontroller runs a 5 V bus, since an on-board level shifter and 3.3 V regulator sort out the voltages for you either way - or take the sensor's analog/PWM signal directly from the 2-pin OUT header for the simplest possible hookup. 
A DIR jumper flips the direction of rotation, solder jumpers enable or remove the I2C pull-ups on each side, and the AS5600's programmable start and stop positions let you map any part of a turn onto the full output range. It's all open-source hardware on a compact 22 × 22 mm board with two M3 mounting holes - just add a magnet and start measuring angles, today!
