$4 Coin-sized Linux Computer with WiFi

$4 Coin-sized Linux Computer with WiFi

VoCore is a small Linux computer with Wifi that can work as a full functional router. It runs OpenWrt on top of Linux. It contains 32MB SDRAM, 8MB SPI Flash and uses RT5350 (360 MHz MIPS) as its heart. It provides many interfaces such as 10/100M Ethernet, USB, UART, I2C, I2S, PCM, JTAG and over 20 GPIOs but its size is less than one square inch (25mm x 25mm). VoCore was launched in 2014 in a crowdfunding campaign and eventually it was 1937% funded! The $20 module had a lot of fans but most of them, such as students, were not able to afford it.

Designers of VoCore came up with a great solution! VoCore2 Lite is the newest product of the Chinese startup for just $4! A Coin-sized Linux computer, smart router and it is fully open source. With such an affordable module, wireless life will become easier and it will push forward the development of new IoT applications.

It is now live in a new crowdfunding campaign and again it is exceeding expectations with 400% funds in the first 10 days!

It has 300Mbps WIFI, 5 x ETHERNET, USB 2.0 Host, 3 x UART, 1 x SD, 2 x High Speed SPI, 3 x I2C, and 40+ GPIOs. It can be programmed in C, Java, Python, Ruby, Javascript and etc. It has various of docks and thousands of software to enhance its functions and the wireless life.

“People may ask, is that price lower than the cost? The answer is it is not, but it is very very very close to the cost, and only for us with the experience of production VoCore2(we reuse  the VoCore2 tech, test jig, test app, to save cost etc…). Just hope students and other cost sensitive people will have a chance to play with the most advanced IoT board.” – Qin Wei, VoCore co-founder

Using VoCore2 as a router

Compared to Vocore2, Vocore2 Lite has a cheaper Mediatek MT7688N MIPS processor, less memory and storage, WiFi is limited to 150 Mbps and an external antenna is required. With only 74 mA power consumption, VoCore2 will be more efficient than ESP8266, that consume around 250 mA, and it will be easily implemented in various projects.

This is a comparison between the three editions of VoCore


The crowdfunding campaign still have 1 month to go and  you can pre-order VoCore2 ($12), VoCore2 Lite ($4), and other docks starting from $29.
