Librem5 modem as a standalone device we could purchase


#1

Would it be possible to release the Librem 5 modem unit as a separate USB device that we could purchase independently of the phone, without the necessity to buy the whole device?

I hope that making it available as a separate module (pcb with solderpads is fine by my standards) wouldn’t require much of an additional investment (certifications, etc).

This way, the modem itself would become easily accessible to a broader community of hackers, makers and tinkerers, and the cost of software development for this module would be greatly reduced. This would significantly aid in making the modem free in the near future.

Additionally, having a voice-enabled modem that can be installed in a laptop or a desktop, enabling it to perform mobile phonecalls (either via gammu/wammu, PureOS in a VM/native, or direct AT interface), is a really big convenience feature as well. To my knowledge, there are none such devices right now coming from a reputable company that supports user freedoms.

Thanks!

This is the same modem as in the devkit. NetworkManager should support it by default, not sure about ordinary phone calls and texts though, probably doesn’t work but that should be due to PureOS/Debian not supporting that yet.

Nice, thanks!
The source for those dev kits seem to be these guys:

They have the modems in different form factors, including this USB and RS232 version:

and this breakout board:

Note that the phone won’t use the same modem as the dev kit, see Manufacturer of the final modem
