Unlike the similar TL-WR703N, this device has 5 free GPIO pins on a 2mm pitch header and 3.3V and 5V on another 2.54mm pitch header. (and more memory)
top left: GL.INET (modified with 1-wire DS18B20 temperature sensor connected to free GPIO pin.)
top right: TP-Link TL-WR703N
bottom left: Carambola 2
bottom right : Anker 40W 5-poort usb lader, very useful device to supply 5 devices with 5V.
The GL.INET is one of many devices with a Qualcomm/Atheros AR9331 SoC and the OpenWRT operating systeem :
for example :
GL.INET
Arduino Yun
Carambola 2
Dragino
TP-Link TL-WR703N
DPT Board (from Belgium)
etc.
It is very easy to run mosquitto on any of these devices.
(Note that not all of these devices have CE certification)
