A couple of days ago, 2 x AS5600 magnetic encoders arrived.
These use a special magnet and 4 x Hall sensors in the chip to read a 12 bit position. So, less than 1/10th of a degree resolution per rev.
The beauty of these devices is the position reading does not get lost when power is removed. (I think)
I hope to use them as antenna tuning and direction reading.
Here is a video talking about them, and the Arduino code he uses.....
Data sheet....
These chips are I2C devices, but also will output a 12 bit PWM signal.
Not bad for about $5.
Watch this space for more info.

AS5600 magnetic position encoder — Curious Scientist
In this video I show you how to use the AS5600 magnetic position encoder. This is a very powerful chip for projects where you need a precise information about the position of a shaft. Therefore, it is extremely useful for stepper motor-related projects because you can use the sensor to directly meas
