M.2 WWAN Modem break-out board kit

This is v3 of the break-out board for M.2 (NGFF) type cellular / WWAN modems, such as modern LTE/LTE-A and upcoming 5G modems.

It allows you to insert a M.2 modem of 3042 and 3052 size types from any vendor, and it will provide you with:

• micro USB B 3 socket for connection to a USB Host (like your PC/Laptop or Embedded System)
• cable + adapter to connect modem PCIe lane to PCIe x1 slot of a host computer (PC)
• 5V DC input for power supply (USB supply usually insufficient for a modem)
• unused M.2 pins on a 2.54mm break-out header
• SIM card slot for a 2FF-sized SIM, USIM or RUIM card
• second SIM card slot for modems with dual-SIM support
• Jumpers to control PERST, W_DIS, GPS_DIS and RESET lines of modem
• four on-board SMA sockets + MHF4 sockets + jumper cables for attaching Antennas with proper strain relief (as opposed to classic pigtails)

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.

The product does not include a 5V DC power supply nor SIM cards or a M.2/NGFF modem. Please see below product links should you want a power supply and/or USB cable included:

• Desktop-style 5V/3A power supply
