PINOUT
Chapter 2 – Pinout
Multi-Tech Mini PCIe Pinout
Note:
Some modems do not include all the pins.
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.
