<\/a><\/p>\nLimeSDR Micro M.2 SDR card specifications:<\/p>\n
SoC \u2013 NXP LA9310<\/a> programmable baseband processor<\/p>\n Vector Signal Processing Accelerator (VSPA) Gen 2 up to 80 GFLOPs Storage \u2013 512 Kbit EEPROM memory for NXP LA9310 initial configuration Lime Microsystems LMS7002M RF transceiver 3x MHF4 RF (TX, RX1 & RX2) Host Interface \u2013 PCIe Gen 3 x1 via M.2 Key -B+M edge connector 4x GPIOs 3.3V on GPIO connector Sensor \u2013 TMP1075NDRLR temperature sensor Rakon E6245LF 30.72 MHz VCTCXO Misc<\/p>\n 2x Green LEDs Power Supply \u2013\u00a0 3.3V via M.2 edge connector LimeMicro has offered SDR solutions based on the LMS7002M RF transceiver for years<\/a>, but they were all FPGA-based<\/a> so far. They\u2019ve now switched to the NXP LA9310 ultra-low-power baseband processor for applications needing to meet specific size, weight, and\/or power requirements.<\/p>\n It\u2019s still 100% programmable, and the company points to the NXP LA9310 Reference Manual<\/a> and VSPA2 Instruction Set Manual<\/a> both available without NDA, open source VSPA kernels<\/a> for functions such as FFT, inverse FFT, CRC generation, FIR filters, mixer, and modulation\/demodulation (some compatible with MATLAB), as well as the existing documentation for the LMS7002M chip<\/a> which is supported by the Lime Suite NG driver stack<\/a> and the wider SDR ecosystem with integration with projects such as SoapySDR, GNU Radio, Amarisoft 4G\/5G, OpenAirInterface, and srsRAN. The company will also release the hardware design for the M.2 module, and the\u00a0 DSP firmware<\/a> and Arm firmware<\/a> have already been released on GitHub.<\/p>\n The company also designed the LimeFEA HF Micro to add a third receive path with a frequency range of 0 \u2013 30 MHz to LimeSDR Micro with the following key features.<\/p>\n Medium Wave (MW) broadcast notch filter 0 \u2013 2 MHz LPF 90 dB gain Two other products are the LimeSDR Micro Pro, which combines the LimeSDR Micro and the LimeFEA HF Micro to provide a USB4 (40 Gbps mode only) peripheral with an aluminum enclosure, and the LimeFEA M.2 2280 full-size PCIe x4 card with a 2\u00d72 MIMO RF front-end (RFE), which integrates low-noise amplifiers in the receive paths (100 MHz to ~4 GHz receive frequency range) and power amplifier (PA) drivers in the transmit paths (100 MHz to 6 GHz transmit frequency range).<\/p>\n \u00a0<\/p>\n Lime Microsystems had launched the LimeSDR Micro M.2 SDR card and associated products on Crowd Supply<\/a> with a $100,000 funding target. Rewards start at $199 for the LimeSDR Micro basic and $299 for the LimeSDR Micro GNSS. A pledge of $199 is asked for the LineFEA HF Micro card,\u00a0 $299 for the LimeFEA M.2 2280 PCIe card, and $799 for the LimeSDR Micro Pro system. Shipping adds $8 to the US, $18 to the rest of the world, and deliveries are scheduled to start by September 30, 2026.<\/p>\n Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later in 2011.<\/p>\n Support CNX Software!
