The LimeSDR Micro M.2 2280 software-defined radio (SDR) card combines an NXP LA9310 baseband processor and a Lime Microsystems LMS7002M transceiver, and targets integration into portable or embedded solutions with a spare M.2 PCIe Gen3 x1 socket. 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. LimeSDR Micro M.2 SDR card specifications: SoC – NXP LA9310 programmable baseband processor Vector Signal Processing Accelerator (VSPA) Gen 2 up to 80 GFLOPs Control Processor – Arm Cortex-M4 at up to 307 MHz Storage – 512 Kbit EEPROM memory for NXP LA9310 initial configuration RF Lime Microsystems LMS7002M RF transceiver Channels – 1T2R expandable to 1T4R via […]

With the price of RAM getting out of control, it might be a good idea to remind Linux users to enable ZRAM so they can get better performance without upgrading memory, or save money on their next single board computer by selecting a board with the right amount of memory.

I had already written about the subject when I enabled ZRAM on a ODROID-XU4Q in 2018 using zram-config, and did the same on my Ubuntu laptop at the time. In recent days, I found Firefox crashing often due to running out of memory on my system with 16GB of RAM, and the Linux 7.0 release reminded me about ZRAM, since there were some related changes. So I decided to check the current swap configuration on my Ubuntu 24.04 laptop:
