7 | It allows you to insert a mPCIe modem from any vendor, and it will provide you with: |
||
8 | |||
9 | * mini USB socket for connection to a USB Host (like your PC/Laptop or Embedded System) |
||
10 | * 5V DC input for power supply (USB supply usually insufficient for a modem) |
||
11 | * all unused mPCIe pins on a 2.54mm break-out header |
||
12 | * SIM card slot for a 2FF-sized SIM, USIM or RUIM card |
||
13 | |||
14 | Particularly the break-out header is useful to get access to various signals exported in a non-standard fashion by some modem models, such as digital audio PCM. |
