The WAVEFORM 3 CLICK is a Click board™ from MikroElektronika, a maker of embedded electronics products. The board is a full-featured, compact signal generator which utilizes the AD9837 on-chip direct digital synthesis device. It uses SPI (Serial Peripheral Interface) commands for programming frequency, phase, and output amplitude and also enables users to shape waveforms from the output pins of the AD9837. This Click board™ operates with 3.3 VDC. It supports a full-scale prototype board, allowing users to test code and functions without dealing with soldering. With the preloaded firmware, the WAVEFORM 3 CLICK board can be used as a signal generator out of the box. The board is perfect for use in projects such as hearing aids, audio and video systems, sensor control systems, public address systems, etc. Additionally, it is pre-calibrated and adaptable to the user’s needs, meaning it can be easily adjusted in terms of amplitude, phase, and frequency.
