WARNING
Some off-the-shelf mini-PCIe 4G modules are not compliant to standard mini-PCIe
interface. They use 1.8V I/O signals instead of standard 3.3V I/O and may have signal
conflict. Please consult with Neousys for compatibility when in doubt!
Installing an incompatible 4G module may damage the system or the module itself may be
damaged.
