The SDR-widget is an open-source hardware solution designed for digital signal processing of audio streams from SDR receivers. Utilizing MLAB modules, it bridges the gap between SDR receivers with analog output and various software tools, allowing precise control of SDR components via I2C and USB. The device operates as an audio card or as a specialized interface for handling SDR protocols like GHPSDR, making it versatile for radio amateurs, researchers, and developers interested in software-defined radio (SDR) systems.
The SDR-widget is a modular SDR interface built from MLAB components, primarily the ADCaudio and AT32TQ144 modules. It digitizes analog signals from SDR receivers, allowing seamless integration with software for signal processing. The device supports multiple operational modes and can output data over USB or as a standard audio stream.
This project was developed to provide an affordable, flexible, and open-source solution for handling analog audio signals from SDR systems. It enables experimentation and customization in fields such as amateur radio, radio astronomy, and digital signal processing, addressing the need for precise and adaptable SDR data-handling tools.
The SDR widget stands out due to its modular architecture, enabling users to customize and expand functionality using MLAB modules. It offers high-resolution data processing (24-bit, up to 192 kHz sampling) and supports multiple configuration modes, making it suitable for a wide range of applications, from basic audio capture to advanced signal analysis.
