-First-Generation Mesh Extenders:+==== First-Generation Mesh Extenders (deprecated) ==== 
 + 
 +The earlier phase of development was based around TP-Link MR3020 wireless routers, and is now fully deprecated.  For people wanting to build a Mesh Extender compatible device, they should refer to the second-generation Mesh Extender documentation above, as it is possible to build a compatible device using a GL-INET AR150 wireless router, which is superior in all ways to the TP-LINK MR3020, not the least being that the GL-INET devices have an open boot-loader, a proper header for the onboard UART, four times the flash, and twice the RAM.
