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.

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.
