h1. ngff-cardem: M.2 (NGFF) WWAN modem + SIM Card emulation board

{{>toc}}

This is a small carrier board for M.2 (NGFF) type cellular / WWAN modems with built-in SIMtrace2 (cardem, trace, ccid) support.

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

* microUSB-B (3.0) socket for connection to a USB Host (like your PC/Laptop or Embedded System)

* DC input for power supply (USB supply usually insufficient for current peaks of a modem)

* 1x SIM card slot for a 2FF-sized SIM, USIM or RUIM cards (dual-SIM)

* built-in SIMtrace2 support for all of its modes

** @cardem@: emulate a SIM card towards the modem (useful for remote sim, e.g. using [[osmo-remsim:]])

** @trace@: trace the communication between physical SIM card and modem

** @reader@: access the physical SIM card slot as a CCID reader from the host (firmware not implemetned yet)

** @mitm@: perform man-in-the-middle between physical SIM card slot and modem (firmwre not implemented yet)
