AS5030 Magnetic Rotary Sensor

Your kit contains two AS5030 magnetic rotary sensor boards. These are designed for connecting to the motor controller.

The AS5030 IC is manufactured by Austria Microsystems, and the datasheet can be found on their website. You should consult this datasheet should you need information about the AS5030's performance.

Connecting up the AS5030

First, identify the connections illustrated in Figure 1 with those on your AS5030 board. Then make the following connections, you will need to directly solder wire onto the pads on the AS5030. Remember to follow the wiring colour convention (Black = GND; Red = +Ve).
  1. Connect the +12V connection on the AS5030 to the +12V connection to the motor board
  2. Connect the GND connection on the AS5030 to the GND connection on the motor board
  3. Connect the DIO connection on the AS5030 to one of the four feedback pins on the motor board.
  4. Connect the CLK connection on the AS5030 to one of the four feedback pins on the motor board.

Positioning the AS5030 and Magnet

For information on orientating your AS5030 board and magnet, consult the datasheet (website).

AS5030 Board LEDS

The AS5030 board has three LED outputs:
  1. Magnetic Field Strength: If this LED is lit, then the magnet is too far away from the AS5030 chip.
  2. PWM: The intensity of this LED changes as the polarity of the magnet over the AS5030 chip is reversed.
  3. Power LED: This LED is on when power is connected to the board. If this light is not on, check that you have wired up the +12V and GND connections correctly.
