Just curious, but I was trying to help someone with a Raspberry Pi Zero W wifi issue the other day and had trouble finding sny info about the wireless chipset used. I couldn't find it listen anywhere on the site, or several tech review sites, only extremely useless information on the 802.11 versions support. If it recall correctly, it didn't even show up in the schematica. Luckily wikipedia had the name of the chipset used, but I don't get it. Why does their official documentation seem to be so secretive?


It's not secretive, it's just that most people are not very interested in the exact type of Wi-Fi chipset used.

You can see the chipset name (BCM43430) on dmesg:

  $ dmesg | grep brcmfmac
