uSDR is designed around a browser-friendly SDR workflow, but it is not limited to the browser.
For users who need native performance, existing SDR applications, or embedded Linux integration, uSDR also supports traditional SDR software stacks across x86 and ARM platforms.
This includes workflows with SoapySDR, gr-osmosdr, GNU Radio, GQRX, USB, WebUSB, and Linux PCIe operation.
| Path | Setup | Best For |
|---|---|---|
| WebUSB | Browser only — no driver install | WebSDR workflows, demos, education |
| Native USB | SoapySDR + GNU Radio / GQRX | Cross-platform native SDR applications |
| Linux PCIe | Kernel driver + carrier board | High-throughput, embedded deployment |
Native SDR software support
Many SDR users already rely on established tools such as GNU Radio, SoapySDR, osmocom-fft, and GQRX. uSDR is designed to fit into these existing ecosystems instead of forcing users into a single software path.
Native-mode support is important when users need:
- maximum performance
- compatibility with existing tools
- custom GNU Radio flowgraphs
- Linux system integration
- PCIe-based streaming
- low-level driver control
- embedded deployment
The result is a flexible platform that supports both modern web workflows and traditional SDR development environments.
ARM and NVIDIA Jetson support
uSDR software libraries and PCIe driver support are compatible with ARM platforms. Wavelet Lab has tested uSDR workflows on NVIDIA Jetson TX2, and the software direction also supports embedded ARM systems where USB, WebUSB, or PCIe integration is available.
This matters because many edge RF applications are deployed on embedded computers rather than desktop PCs.
NVIDIA Jetson and ARM-based SBCs are commonly used for:
- edge AI processing
- robotics
- field-deployed sensing
- portable RF systems
- embedded wireless gateways
- autonomous systems
- signal monitoring nodes
Combining SDR input with embedded compute creates a practical path for edge RF intelligence.
USB, WebUSB, and PCIe paths
uSDR supports multiple connectivity paths depending on the user's system and performance requirements.
USB and WebUSB provide simpler setup and broader compatibility.
PCIe provides higher performance and lower-level integration, especially for Linux-based systems.
This gives users a choice between convenience and performance:
- browser workflow through WebUSB and WebSDR
- native USB SDR applications
- Linux PCIe operation for higher-throughput use cases
Thunderbolt and adapter workflows
Because uSDR uses an M.2 form factor, it can also be used through adapters. Thunderbolt-to-M.2 SSD enclosures and M.2 adapter boards create additional ways to connect uSDR to laptops and desktop systems.
This is useful for portable SDR setups where users want PCIe-style performance without designing a custom carrier board.
Multi-channel possibilities
The small M.2 form factor also makes it possible to experiment with multi-device configurations using expansion boards and adapters.
While larger synchronized systems are better served by platforms such as xMASS, uSDR's compact size allows creative multi-channel experimentation and embedded integration.
Why native support still matters
Browser-based SDR makes setup easier, but native support remains important for advanced users.
Some applications require existing GNU Radio blocks, high-performance DSP pipelines, direct driver access, custom automation, or system-level integration.
Wavelet Lab's goal is to support both sides: browser-based usability for fast access, and native software compatibility for expert workflows.
