== Technical overview ==
* The board is a module driver board and cannot operate alone; it requires a compatible 5G or 4G module with an M.2 (NGFF) Key B interface.
* Supports 5G modules in 3042/3052 form factor, such as SIM82XX and RM50XQ series.
* Four IPEX-to-SMA antenna connectors allow direct antenna installation.
* A NANO SIM card slot is provided.
* A USB 3.1 Type A port enables connection to a PC, Raspberry Pi, or Jetson Nano.
* An aluminum alloy heatsink cover improves heat dissipation.
* Multi-slots and mounting holes are reserved for integration.
* PCB finish: immersion gold.
* Power and network LEDs plus test pads are available for diagnostics.

== Notes and version constraints ==
* The device cannot operate without a compatible module.
* Compatibility of other M.2 B-Key modules must be verified against the pinout and confirmed by practical testing.
* Speed measurements depend heavily on location, network load, coverage, and carrier limits; lab values are often not reached in the field.
* On Linux, detection can be checked using "lsusb" and "ls /dev/ttyUSB*".
* IPEX connectors are fragile; when removing the module, gently wiggle side-to-side and pull evenly.
* Increased fan noise after prolonged use may be due to lubricant evaporation and is not necessarily a fault.
* Modules lacking USB functionality (PCIe only) are not supported; only modules with USB functionality and matching pinout are suitable.
