+==== Second-Generation Serval Mesh Extender ====
+The [[content:meshextender:2ng|Second-Generation Mesh Extenders]] are the current generation of Mesh Extender hardware, and continue to be under active development.
+{{:content:meshextender:front_3-4.jpg?200|}}
+  * powered by external USB, 12v/24v automotive and/or solar (with MTTP tracking charge controller)
+  * Integrated LiFEPO4/LiIon/Sealed-Lead-Acid battery charger
+  * Custom-designed injection-moulded housing
+  * Designed to meet IP66 environmental resistance
+  * Integrated "Mesh of Things"/"Internet of Things" I/O port
+  * microSD card for bulk storage (reduced power consumption versus USB)
+  * Wi-Fi access point (for devices to connect) and ad-hoc Wi-Fi (between Mesh Extenders)
+  * RFD900/RFD868 UHF packet radio (up to 4km range line-of-sight, ~200m indoors)
+  * Interface to [[:content:meshextender:externalradios|Codan/Barrett HF Radios]] for very-long-range communications links (support for other radios is also possible)
+  * provides a standard Wi-Fi Access Point for nearby devices (such as smart phones) that do not support Ad Hoc Wi-Fi mode
+  * offers the [[:content:tech:Serval Mesh]] app for Android for download via HTTP so that people can join the [[content:tech:mesh network]] without having previously installed the app
+  * acts as a [[:content:tech:Rhizome]] node, storing and forwarding files and [[:content:tech:MeshMS]] messages
+  * Fully interoperable with 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.
