M.2 2280 SDR (software-defined radio) module cnx-software.com/2026/04/15/… @LimeMicro LimeSDR combines an @NXP LA9310 baseband processor with an LMS7002M RF transceiver. The module is offered in a 1T2R configuration by default, but can be expanded to 1T4R via an FPC connector, supports a 30 MHz to 3.8 GHz frequency range, and up to 100 MHz bandwidth. Target applications include 4G LTE/5G, future RAN research, custom user equipment/modems, drone communications, IoT, satellite communications, and custom waveform generation. It's a fully open-source hardware project with hardware design files, DSP and Arm firmware, and more. The company also provides a companion card to handle a frequency range of 0 – 30 MHz, a PCIe x4 card, and a complete USB4 system based on the M.2 SDR card.
