Kit Description
The AS5030 Demoboard provides a platform to quickly evaluate the performance of the AS5030 Rotary Encoder SOC. A USB cable and desktop GUI is provided to fast, user-friendly access to the AS5030 output.
The AS5030 is a contactless magnetic rotary encoder for accurate angular measurement over a full turn of 360°.
It is a system-on-chip, combining integrated Hall elements, analog front end and digital signal processing in a single device.
To measure the angle, only a simple 2-pole magnet rotating over the center of the chip is required.
The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 8 bit = 256 positions per revolution. This digital data is available as a serial bit stream and as a PWM signal.
In addition to the angle information, the strength of the magnetic field is also available as a 6-bit code.
Data transmission can be configured for 1-wire (PWM), 2-wires (CLK, DIO) or 3-wires (CLK, DIO, CS).
A software programmable (OTP) zero position simplifies assembly as the zero position of the magnet does not need to be mechanically aligned.
A power down mode together with fast startup- and measurement-cycles allows for very low average power consumption and makes the AS5030 also suitable for battery operated equipment.
