Vocore2 Lite is a $4 Linux MIPS WiFi Module based on Mediatek MT7688AN SoC (Crowdfunding)

I’ve already written about Vocore v2 Crowdfunding campaign, where the second generation Vocore WiFi module supports audio, PoE, and ultimate dock, and price starting at $12. But there has been some development since the launch of the campaign, as the developer received request for a cheaper board, and after looking into it, has now added Vocore2 Lite WiFi module reward for only $4, or $7 once shipping included.

vocore2-liteHe obviously had to make some trade-offs to bring the cost down, but the Lite board impressively still keep many of the same features.

Compared to Vocore2, Vocore2 Lite has a cheaper Mediatek MT7688N MIPS processor, which is already used in board such as Mediatek LinkIt 7688, Onion Omega2, and Widora-NEO, less memory and storage, WiFi is limited to 150 Mbps and an external antenna is required, and the PCIe 1.1 interface is gone. The dimensions appear to be the same, so the dock should be compatible too, provided PCIe is not needed. Software support will be the same with OpenWrt/LEDE Linux distribution.

If you are interested, you can pledge $7 for Vocore2 Lite on the Indiegogo page with delivery planned for January 2017. There aren’t any pledge combining Vocore2 Lite with a dock so far.

Thanks to Freire for the tip.

What is the price of the required external antenna? 2 USD? 4 USD?

sorry but I see mediatek and I automatically shudder!

Very nice find! Thank you!

FYI: For those who don’t know the SPI on that particular chip is fundamentally broken. So this means that everyone will distribute the boards Onion2, widora, mediatek’s linkit, … with a broken SPI.

If the Orange Pi Zero ever becomes real, so many of these tiny Linux boards are going to look pointless and expensive. Orange Pi One itself makes this look expensive.

@Ali
But you will have a hard time getting consumption of Orange Pi One below 750 mW (150 mA). It’s possible with Armbian’s h3consumption tool but then you also need to build USB and Ethernet drivers as modules to unload them when not needed (then you get below 100 mA).

Can you provide any more information about how SPI is “broken” ?

@Mum An excerpt from the MT forum: I’m trying to hook up an LCD to the SPI port (SPI CS1) on the LinkIt Smart 7688. It appears the most significant bit of data writes isn’t being sent reliably. If I send 0x8E, my analyzer shows 0x0E. If I send 0xCE the analyzer shows 0xCE. I’ve tried this with several different values and don’t see any pattern. I’ve used both C and Python (MRAA) to send the data and the problem is in both places. I’ve also disconnected the MISO line from the LCD thinking the LCD might be affecting the… Read more »
