Hi, we are using the BG95-M3 Mini PCIe module. Is there an easy and fast way for out microcontroller to detect if the miniPCIe module is present? I.e. is there a pin that will always be driven high or low that we can read? I’m currently using a timeout on the UART, but this can take some time.
When the module is installed correctly and the power supply is normal, the LED lights up to indicate that the module is present and recognized by the system. If the LED is off, it indicates that the module is improperly installed or the power supply is faulty.
And there isn’t a dedicated pin that is always driven high or low.
