All that is needed is a magjack on the carrier. What this particular carrier does is to provide a *twin* magjack, wire the appropriate CM4 pins to half of it, and wire the other half to a LAN7800 USB-to-GigE adapter. The latter is then wired up to the CM4 via a 4-port USB hub chip, so there are also three USB ports (one on a header, two as physical ports).<br><br>All but the cheapest of the CM4 models also include a single-channel, dual-band wifi/BT chip. This requires only an antenna to make it an austere but probably usable AP. For better performance, a multi-channel wifi adapter could be plugged into the USB header, and the cheapest CM4 "Lite" would probably then be sufficient.<br><br> - Jonathan Morton<hr>Cerowrt-devel mailing list<br>Cerowrt-devel@lists.bufferbloat.net<br><a href="https://lists.bufferbloat.net/listinfo/cerowrt-devel">https://lists.bufferbloat.net/listinfo/cerowrt-devel</a><br></pre></blockquote></div><br>-- <br>Sent from my Android device with K-9 Mail.
