Recent pi without wireless connectivity available?

[piuser5644154]

Hi,

for an airgapped hardware-wallet I am looking for a somewhat recent sbc that has no wireless connectivity on a hardware level. Is there any Pi out there, that is available for sale new and sealed, that has no built in BT/Wifi module?

Preferrably one compatible with pi hats for nvme etc.

Thank you for your input!

Pi do not make such a device. It is possible to modify the Pi 4 to disable the wireless chip, but it is not an easy job.

picking a CM4 without Wifi/BT should be simple, add it to the baseboard + NVMe --> done.

The only Pis that come with an exposed PCIe lane that can be used to create an M.2 connection are the CM4 (with a suitable base board and the Pi5. And the Pi5 is the only one really set up to connect a PCIe lane to a HAT. Unfortunately for your project, the Pi5 has WiFi/BT built in.

Are you willing to mod the PCB? I suspect cutting the traces to the built in antennae would make the wireless non functional. Certainly can disable it in software. You have to also deal with securing the ports, so folks cannot sneakernet stuff out, or just connect a WiFi dongle.

I would go with cut the traces, disable it in software, epoxy in the SD with a read only OS, and then put in in a tamperproof metal case. It depends on how bulletproof you want your solution to be. Just putting the PI in an all metal case, makes the WiFi mostly useless.
