The board provides a wide range of analog and digital output signals, which enable the user to quickly evaluate the performance of the AS5043 magnetic encoder in different applications. The board features an on-board DAC for direct angular measurements with resolutions up to 0.025 degrees as well as pulse width modulation (PWM) output for applications requiring high-excitation frequencies and rapid position updates. The board also includes a configurable high-resolution quadrature decoder for precise angular measurement and interfacing with other motion control systems.

Working Principle of AS5043 DB V2

The core of the AS5043 DB V2 is the AS5043 magnetic encoder that utilizes the Hall effect to detect a magnetic field which is generated by an external magnet positioned inside the board’s mechanical shaft. The AS5043 measures the field strength and direction of the magnetic field to determine the current angular position of the shaft. This data is then processed by an onboard processor to provide an analog or digital output signal that can be used by an external system for motion control.

The board is powered by an external power supply and is connected to an external system such as a microcontroller or motion controller via an I²C or UART interface. The I²C and UART interface allow the user to easily configure and access the AS5043 and board parameters for further optimizations. Furthermore, the board contains two LEDs to indicate power and communication status and three buttons that allow the user to configure the board settings and store the current measurement values in the on-board non-volatile memory.
