M.2 5G modem on Rock Pi 4?

#1

I have been looking through the forum and wiki for info but the only learnt Rock 3 supports 5G module through M.2. Does this go the same for Rock Pi 4? I am looking for specifically Rock Pi 4 Plus.

Are M.2 5G modules supported in Rock Pi 4 Plus? Are there modems that are know to be supported?

Thank you all in advance,

Best,
Tony

Can specify which m.2 5G module do you want to use?

Thank you for your prompt response!

There are a few we’re looking at. all are powered by Qualcomm’s Snapdragon X55 modem though.

Models we’ve considered so far, to name a few:

  • SimComm SIM8200EA-M2
  • GosunCN GM800
  • Waveshare SIM8202G-M2 / SIM8200EA-M2

Are these sensible choices?

@jack @hipboi any updates?

Hello, still looking at the options here :slight_smile: @jack @hipboi

Better to check their compability with linux and arm SBC in total.

Sorry for reopening a stale post, but I find myself in the same boat. Can the op please provide any info on where this went? were you able to integrate any of the 5G modules? any advice? Thanks

If you’re still looking for that, there are two good options.

  1. A modem that supports USB - just stick it into an m.2 to usb enclosure e.g. this .

  2. For a PCIe modem that doesn’t support USB, you’ll need two adapters - one from m.2 m key to m.2 a and/or e key or minipcie, the other from whatever interface you chose to b key with SIM slot, e.g. this if you went a/e key route. Or you can just use a miniPCIe modem with this.

Rock 4 runs OpenWRT very well, it’ll be smooth sailing as long as the modem is supported by it.
