was $13.99 Special Price $10.49
Availability: In stock


Breakout board of the AS5601 (ams AG) magnetic absolute rotary encoder with 12-bit (4096ppr) resolution to 2.54mm pitch. A neodymium magnet is included.
Power supply pins for 5V, 3.3V, and GND, and pins for I2C and A/B phase incremental outputs are provided. The supply voltage is 5V or 3.3V.


  • High resolution: 4096ppr (incremental output is up to 2048ppr)
  • Magnetic type enables non-contact angle measurement, excellent reliability and durability
  • Interface
    • I2C: Angle reading and operation setting are possible by accessing the config register
    • Incremental output: Quadrature output of A/B phase with configurable resolution from 8ppr to 2048ppr
  • Sampling time: 150μs
  • Capable of reading values even when the axis center of the AS5601 and neodymium magnet is off by about 1mm
