VoCore is priceless for me.

Finally VoCore v0.3 PCB comes to my home today. Now there is no jump wire anymore.

So happy, now I have a board that I have full control on it.

I have a raspberrypi, I can not full control it and I have to buy a 30USD camera, that is expensive. I want to DIY one, but camera interface is not opened. I really hate that, I just want to control every corner of my own board. That is one important motivation for me to make VoCore. I think if you want every one to use it for study or learn programming, it is better to open them all.

But for my module, in my further plan, I will make a camera based on OV2640 or OV3660 which supply JPEG format output, the camera price will be under 10USD.

Next version should be the final version, v0.4, in that version I will use “Semi-hole technology”(searched from google, in Chinese it should be 半孔工艺) to make the board smaller. Now its size is 27mm x 27mm, a little bigger than 1RMB coin(25mm). Next version it will be 24mm x 25mm with a on board Ceramic Antenna, but I am not sure about that, I need to test on 0.3 first to make sure ceramic antenna works well on my side.

After wifi test/GPIO test and other test is done from my side, I will make about 100p, and try to sell it at 10USD on taobao/ebay. Hopefully then more people will help me develop it and make this one better or even smaller. Software and hardware will be all open forever. 🙂

This module, in some situation, it is better than arduino for study embed.

VoCore v0.3: The Smallest/Cheapest Router Module in the World :)

From my search online, now I am sure, VoCore0.3 is the SMALLEST/CHEAPEST/28GPIO&other interface Linux Router Module in the World 🙂

The price should be less than 10USD. But it can do job as a full function linux MIPS computer with wifi.

在网上搜了半天,现在我可以确定,VoCore v0.3是世界上最小的最便宜的,28个GPIO及其他的各种接口最全的Linux路由器模块。

批量生产价格应该在60元人民币以下,但是它其实就是一台带wifi的linux小电脑。

Waiting for new 0.3 PCB from factory…It is a long time…

So I decide to complete that “jump wire” VoCore v0.2. After several attempts, it works now!

This are some screen captures 🙂
