Multi-Tech Mini PCIe Pinout
Note:
Some modems do not include all the pins shown above. Refer to your model’s Device Guide for model
specific pinout information.
SDIO can operate up to 25Mhz. Treat the SDIO traces to Host like a bus and keep the bus length as short as
possible. Multi-Tech recommends adding series termination resistors on all the SDIO traces.
