Yes, seems that Purism is now using RS9116 instead of AR9462 at their new revisions of Librem 5
Although RS9116 has the better tech specs, that's less software freedom because of the closed source proprietary firmware. That's the first time I hear about this Redpine Signals company, because of their small marketshare it's less likely that someone would reverse-engineer their firmware - but on the other hand it may be possible to petition them to release the sources.(08-24-2022, 02:06 AM)linmob Wrote: The state of fully free WiFi chips that can be connected in embedded devices (meaning not via PCIe or USB, but via technologies like SDIO) is sadly very disheartening - afaik there is actually no option (which is why PINE64 started that Nutcracker challenge).
Regarding the lack of SDIO freedom-respecting adapters: do you think it may be possible to use a USB one (i.e. ath9k_htc) via some USB-to-SDIO converter?
