We’re excited to announce the launch of our crowdfunding campaign for xSDR — the next evolution of embedded software-defined radio.

Like uSDR, xSDR is built around simplicity, accessibility, and collaboration, now with expanded performance and flexibility.

xSDR is a compact, single-sided M.2 software-defined radio designed for seamless integration into modern computing platforms. The “x” stands for extended, delivering extended bandwidth and multi-channel operation in the same minimal footprint that defined uSDR.

You can configure and operate xSDR directly from a browser, and collaborate through cloud-based workflows using the wsdr.io platform. Build, control, and share RF applications without complex setup or driver overhead.

From uSDR to xSDR & sSDR – A Growing Ecosystem

xSDR preserves the embedded-first philosophy and compact form factor, while expanding RF capability and flexibility. It represents the next step forward, designed for users who need multi-channel operation, higher performance, and deeper integration into modern computing platforms.

Together, uSDR, xSDR, and sSDR form a scalable ecosystem — from compact embedded nodes to advanced multi-channel systems. We invite you to explore the campaign page, share your feedback, and follow the campaign for updates. Join us in bringing the next generation of embedded SDR to life.
