One thing I realized I forgot: If you do end up ordering this, or making one: MiniPCIe cards require a non-default height. I think it was 1.0mm total PCB height, but do cross-check me on that.

Sure thing. I used EasyEDA (Std) to design it. It seems KiCad can import it quite successfully as well via "Import Non-KiCad Project -> EasyEDA (JLCEDA) Std Backup" and then pointing it at this ZIP.
Backup ZIP: https://github.com/Doridian/meshtastic-firmware/releases/download/pcb/MiniPCIELORA_d1dfdf68ba6c4ee6a88708359c46a948.zip
Also, this whole repo which adds support to meshtastic for my PCB (just defines the pinout pretty much): https://github.com/Doridian/meshtastic-firmware
The only non-obvious thing about the PCB design: You need to bridge either +3V3 or +3V3AUX to VCC on "H2" (+3V3AUX is powered during standby on some laptops, +3V3 is never, hence the option)

I can send the PCB schematics over if you want. :3
Not that it really is anything complex in the first place x3

The little Meshtastic node inside of my ThinkPad T420s is surprisingly good (one of the antennas measured quite well for the frequencies used, so I wired it in. I assume it was meant for GNSS? Or UMTS?).
The PCB is a quick custom design I whipped up in EasyEDA to connect an ESP32-S3 with an SX1262 radio chip. It uses the USB pins of the MiniPCIe slot originally intended for a WWAN modem in this laptop :3
