We had recently received the prototype v2 of the m.2/NGFF WWAN modem breakout board and are happy to report that it immediately worked for both USB 3.0 super-speed as well as for PCIe. All debug results and reworks from v1 have been incorporated in this v2.
Design validation has completed, which means a first manufacturing batch is in up in the pipelnie, and we expect boards to become available from the sysmocom webshop in some 4-6 weeks (maybe a bit later due to christmas holidays).
As usual, as the project is an Open Source Hardware, and anyone can go ahead and build their own boards, see http://git.osmocom.org/osmo-small-hardware/tree/ngff-breakout for the design files.
fun fact: The part most difficult to source is the M2x3 wide-flat-head screw that holds the M.2 card in place.
