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)

h2. Where to buy
h3. Open Source Hardware
The general idea of Open Hardware projects is that anyone is allowed to build the design. So feel free to take the design files and build it yourself, either modified or unmodified. Please make sure you always
* attribute the original author (Attribution)
* release any changes to the design files under the same terms (Share Alike)
