Breakout board of the AS5600 (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, analog, PWM outputs are provided. The supply voltage is 5V or 3.3V.

Feature

• High resolution: 4096ppr
• 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
  • Analog output: Analog voltage value corresponding to angle
  • PWM: PWM signal with duty ratio corresponding to angle
• Sampling time: 150μs
• Capable of reading values even when the axis center of the AS5600 and neodymium magnet is off by about 1mm

Included Items

• Board ×1
• Neodymium magnet ×1

Specification

• Board size: W20 x D13.5 mm
• Mounting holes: 15mm pitch, M3 x 2
• Magnet size: Φ6 x 2.5 mm
• Magnetization: Diametric
• When supplying 5V for power supply voltage, leave the 3.3V pin open. When supplying 3.3V, also supply 3.3V to the 5V pin.
• DIR pin is connected to GND. PGO pin is unconnected.

How to mount

1. Attach the included magnet to the center of the rotor shaft.
2. Attach the board to the fixture so that the center of the AS5600 aligns with the center of the magnet.

Program example with Arduino

Angle acquisition via I²C

Source code

Minimum code

#include <Wire.h>
#define AS5600_AS5601_DEV_ADDRESS      0x36
#define AS5600_AS5601_REG_RAW_ANGLE    0x0C

void setup() {
  // I2C init
  Wire.begin();
  Wire.setClock(400000);

  // Read RAW_ANGLE value from encoder
  Wire.beginTransmission(AS5600_AS5601_DEV_ADDRESS);
  Wire.write(AS5600_AS5601_REG_RAW_ANGLE);
  Wire.endTransmission(false);
  Wire.requestFrom(AS5600_AS5601_DEV_ADDRESS, 2);
  uint16_t RawAngle = 0;
  RawAngle  = ((uint16_t)Wire.read() << 8) & 0x0F00;
  RawAngle |= (uint16_t)Wire.read();
  // Raw angle value (0 ~ 4095) is stored in RawAngle
}

void loop() {
}

Obtaining angles via analog pins

Source code

Minimum code

#include <stdint.h>

void setup() {
  uint16_t AnalogValue = 0;
  AnalogValue = analogRead(0);
  AnalogValue &= 0x03FF;
  AnalogValue = 0x03FF - AnalogValue;
  // Angle value (0 ~ 1023) is stored in AnalogValue
}

void loop() {
}
