The WiFi Heart

A project log for WiFi Rocks

I purchased a tiny WiFi router from Indiegogo. Time for an IoT Pet Rock

As I'd described earlier, the heart of this rock is going to be a mini Wifi module I am getting from IndieGogo called "VoCore". Now I haven't yet received the final product, but I have got one of the Alpha boards. One of the problems with the Alpha boards is that there's a capacitor in the wrong spot. So I did my best with a soldering iron, but I don't think it worked, as the module boots, but the Wifi doesn't work.

In case you haven't read the details of the VoCore module, it's core is made from a Ralink RT5350F SoC. To quote the RT5350F datasheet: 

"The RT5350 SoC combines Ralink’s IEEE 802.11n draft compliant 1T1R MAC/BBP/PA/RF, a high

performance 360 MHz MIPS24KEc CPU core, a 5-port integrated 10/100 Ethernet switch/PHY and a USB


This SoC is usually found in 3G travel routers. Here, it runs the OpenWRT Linux distribution, which opens up the options on what we can do with the rock!

I'll have to try and get the wifi sorted, as I don't think the final module will arrive before the end of the Hackaday Prize closing date.

In the meantime, I'll keep working on the power supply side. Hopefully a schematic in a few days. I'm still trying to decide how do do it, as I don't want the system to run LiPo's down til they're empty, although I could just use protected 18650 batteries, and not worry about any additional circuitry. Ahh. Decisions. Decisions.....
