AS5040-ASST AS5040 Programmable contactless magnetic rotary encoder sensor module replaces optical encoder for arduino
Board size 28MM*22MM, power supply voltage 3.3-5V
 
An overview of the
The AS5040 is a contactless magnetic rotary encoder for precise measurement
Measure the entire 360° Angle. This product is a system on a chip, in
Integrated Hall components, analog front end and digital are integrated in a single package
Data signal processing function.
To measure the Angle, simply equip one above the center of the chip
A rotating bipolar magnet will do. The magnet can be mounted on top of the IC or
Below.
This absolute Angle measurement can immediately indicate the angular position of the magnet,
Its resolution is 0.35°, or 1024 positions per turn. digital
Data can be given in the form of a serial bit stream or a PWM signal.
In addition, user programmable incremental output is also available, making this
The chip is ideal for replacing a wide range of optical encoder products.
The AS5040 has a built-in voltage regulator that allows it to operate at 3.3V or 5V
Under the supply voltage.
