• Wavelet Lab’s xSDR is a tiny, single-sided M.2 2230 software-defined radio (SDR) module designed for integration into laptops, embedded systems, and edge computing devices. • A successor to thecompany’s previous uSDR, the “x” in xSDR stands for “extended,” adding 2×2 MIMO support and a wider frequency range to the same tiny footprint. • The module is built around theLime Microsystems LMS7002MRFIC and an AMD Artix-7 XC7A50T FPGA as found in theLimeNET Micro 2.0 Developer Edition board. • This combination allows for a tuning range of 30 MHz to 3.8 GHz and a sample rate of up to 122.88 MSPS, making this SDR suitable for cellular research (LTE/5G), spectrum analysis, satellite tracking, and high-speed data links (with two modules). • Wavelet Lab’s xSDR specifications: RFIC - Lime Microsystems LMS7002M programmable RF (FPRF) transceiver IC FPGA - AMD Embedded XC7A50T (Artix-7) with 52,160 logic cells RF capabilitiesChannels - 2×2 MIMO (2x RX, 2x TX)Frequency Range - 30 MHz to 3.8 GHzBandwidth - 0.5 MHz to 90 MHzSample RateSISO - 0.1 MSPS to 122.88 MSPSMIMO - 0.1 MSPS to 80 MSPSClock Stability - 0.5 PPMConnectors - 4x MHF4 RF connectors Channels - 2×2 MIMO (2x RX, 2x TX) Frequency Range - 30 MHz to 3.8 GHz Bandwidth - 0.5 MHz to 90 MHz Sample RateSISO - 0.1 MSPS to 122.88 MSPSMIMO - 0.1 MSPS to 80 MSPS SISO - 0.1 MSPS to 122.88 MSPS MIMO - 0.1 MSPS to 80 MSPS Clock Stability - 0.5 PPM Connectors - 4x MHF4 RF connectors Storage - EEPROM AT24CSW020 (2 Kbit) USB - USB 2.0 PHY (USB3330) Host Interface - M.2 2230 A+E key edge connector (supports both USB 2.0 and PCIe 2.0 x2) Expansion12+2 pin 1.8V GPIO header (compatible with uSDR pinout)External clock synchronization for multi-channel phase-coherent arrays (xMASS) 12+2 pin 1.8V GPIO header (compatible with uSDR pinout) External clock synchronization for multi-channel phase-coherent arrays (xMASS) MiscCrystal oscillator (NT2016SA 26 MHz)Temperature sensor (TMP114) Crystal oscillator (NT2016SA 26 MHz) Temperature sensor (TMP114) Power

Article Summaries:

  • Wavelet Lab has launched the xSDR, a 30 × 22 × 2 mm M.2 2230 software‑defined radio that builds on its earlier uSDR. The module uses a Lime Microsystems LMS7002M RFIC and an AMD Artix‑7 XC7A50T FPGA, offering 30 MHz‑3.8 GHz tuning, 2×2 MIMO, and up to 122.88 MSPS sample rates. It connects via USB 2.0 or PCIe 2.0 x2 and supports GNU Radio, SoapySDR, and web‑based wsdr.io. The device is available on Crowd Supply for $549, with a $89 M.2‑to‑PCIe breakout board, and shipping begins July 15 2026. Full schematics and gateware will be released post‑campaign.
