miniPCIe WWAN modem breakout board

Key Features

The main features of the board can be described as follows:

• on-board linear power regulator generating the 3.3V supply voltage for the miniPCIe modem

• USB 2.0 high-speed signals exposed on USB 2.0 mini-B connector (miniB-A cable included)

• 2FF (mini-SIM) slot for RUIM/CSIM/SIM/ USIM

• all unused miniPCIe pins are exposed on a 2.54mm break-out header. This is useful for attaching to non-standard interfaces such as PCM audio busses of modems.

• PERST and W_DISABLE can be configured via jumper

• 3x on-board SMA sockets with U.FL next to them; U.FL to U.FL pigtail cables included. This provides proper strain relief of any antenna connections to the modem.

• Power LED and Modem Status LED

Compatibility

As the miniPCIe modem break-out board adheres to the miniPCIe mechanical form factor and standardized pin-out, it should work with any WWAN modem, irrespective of the supplier.
