Unfortunately I missed the Indiegogo campaign, hope I could buy the Turris Mox + SFP Module soon, it seems really interesting.
But I have some suggestions to make.
MOX B Module
The module is good, but I would suggest to develop another one but with the followings improvements:
M.2 WWAN socket, instead of mPCIe. Recent high performance LTE modems (Sierra EM7565, Quectel EM20,…) uses a M.2 interface instead of mPCIe.
Please, add a second SIM connector. Recent modems all support Dual-SIM. It won’t cost a lot: a connector, ESD protection and a capacitor. It won’t make the BOM a lot more expensive. If there is no space, than use a Micro or Nano SIM connectors.
Last point, unfortunately the Moxtet connector doesn’t support USB 3.0 yet. Hope that in future models it could be added (well, the SoC have to support enough ports too). USB 3.0 will be needed for future 5G modems or Wifi ax cards.
It would be great if you could design the board to operate at temperatures below 0°C. It would open you the market to new customers.
Hope this feedback will help you to improve your product.
