Info

GL-Inet.com creates nice clones of TP-Link WR-703 routers. They run OpenWRT out of the box, and have 2 ethernet interfaces, a 2.4Ghz Wifi (802.11n) radio, a usb2.0 port and 5 free GPIO ports (2mm spacing). Available on dealextreme/alibaba or in the RevSpace vending machine.

A new board design has been releases in September, with slightly modified/improved power circuits. Some requests have been made for the next board redesign (gpio headers in 2.54mm spacing instead of the current 2mm), which will hopefully be made soon.

RevSpace images and packages

Alternative packages and install-images for OpenWrt (trunk) for GL-Connect GL-iNet v1 (GL-iNet-6416A) devices, Build-environment for the GL-Inet, http://glinet.sigio.nl/. You will need the openwrt-ar71xx-generic-gl-inet-v1-squashfs-factory.bin file, md5sum ad2164a70e4ccc9a40f77bf49d3bb472

Note that using a custom build means you can't use the normal repositories for kernel-packages.

OpenWRT

The device runs OpenWRT out of the box, but it's quite easy to build your own image. Since August 2014, the patches are included in OpenWRT upstream.

Hacks

External antenna

Maxell's shopping list for the external antenna modification.

IPX naar RP-SMA pigtail, RG178: [1]
Surface mount IPX: [2]. New(er) PCB's already have these in place. Check your GL-Inet before buying.

including antenna

Mod by Morphje: Range increased to 400+ meter open air range. Signal quality on IBM laptop was 43% @ 400 meter.

Display

Widely sold as the "Nokia5110 display" (but actually most famous for being the display of the Nokia 3310), this 84 × 48 graphical display can easily be added to a GL-Inet and controlled by bitbanging SPI with the GPIO pins. It uses 4 GPIOs, leaving one vacant, if you simply tie CE/SCE to GND.

Wires soldered and plugged in, slot dremeled.
In action, after the display was hot-glued to the case of the GL-Inet.

Note: some of these PCBs come with a current limiting resistor of 150 Ω for the background LEDs, while others don't. Add your own resistor if your board didn't come with a resistor, or the LEDs will wear out very quickly.

Alternate use of the GL-Inet

Note: GL-Inet might not be waterproof

Power over Ethernet

The original WR703n was more "hackable" to add POE. The RJ45 magnetics were separated in a different chip. See: [3]

The GL-Inet uses an magnetics integrated RJ45 jack. See: [4] This will probably that we need to alter the jack by means of an dremel. Update will be follow.
