RP2040 powered waveform generator circuit

The DIY waveform generator is a PCB built and assembled by JLCPCB. It features a RP2040 MCU and an Analog Device's AD9833 waveform generator IC. It is powered by USB and can be programmed the exact same way a Raspberry Pi Pico is. The PCB includes 8 debug LEDs as well as two headers to break out the AD9833 output as well as GPIO from the RP2040.

The motivation for the project was to create a circuit that can output various frequencies for testing audio amplifier circuits. The AD9833 can output any frequency up to 12MHz and can generate square, triangular, and sinusoidal waveforms. As a result, the PCB can be used as a tool for generating a test signal or it can be used for purely educational purposes.

A getting started guide which includes code for blinking the LEDs and generating a 1KHz output sinusoidal waveform is available. For more information on the project, check out my blog at sellerscircuits.com and the getting started guide.
