TinyVision is a compact Allwinner V851S/V851S3-powered Linux board for vision-based applications

Unrelated to tinyVision.ai, the TinyVision development board is a computer vision board from Chinese developer YuzukiTsuru powered by either the Allwinner V851S or the V851S3 and is billed as an “ultimate all-in-one solution for Linux motherboards, IPCs, servers, routers, and more.”

It packs features such as a Cortex-A7 core running at 1200MHz, a 2-channel MIPI CSI input, and an independent image signal processor (ISP) capable of a maximum resolution of 2560 x 1440 in a compact form factor.

tinyvision board and usbttl splitter

The USB port on the device is Type-C but it is also described as USB 2.0, which is weird. Supporting modules include a USB-TTL splitter board that splits the USB-C port into USB and UART ports, an LCD display, a Wi-Fi module, a GC2053 camera, and an RJ45 connector.

TinyVision supports both Linux and a real-time operating system. It can run GNU/Linux operating systems such as OpenWrt 23.05, supports buildroot and mainline Linux 6.7, and offers RTOS support based on RT-Thread + RTOS-HAL. The board is open-source hardware. Schematics, bill of materials, and Gerber files can be found in the TinyVision GitHub repository.

The 64MB version of the board can be obtained for about $9 from AliExpress, with the 128MB board and certain modules also available for purchase. Further information about the TinyVision board can also be found on the YuzukiHD website.

Thank you for the article, very interesting device!
Unfortunately the aliexpress url is 404 for me here in germany (possibly country blocked?)

Thank you for trying to help! Unfortunately I only get tons of random unrelated results here.

me too.

a working link would be nice. Or has the product / seller disappeared from Ali?

It looks like the board is not available to Europeans. Maybe some VAT configuration issue?

or other EU laws / regulation, for example compliancy / safety / warranty?

Google does give an Ali hit, but clicking on it results in “Sorry, the page you requested can not be found:(”

So: retracted? Or not available to certain countries?

Calling the USB-C connection USB2.0 probably just means it doesn’t support the high speed lines, just the USB2.0 D+/D- pairs and *hopefully* the CC lines, but that’s not entirely necessary.

Nice article. I’m not sure how much useful machine vision a board like this can do, but at least it’s cheap?

I was able to order the board in the US, but can’t find a way to buy either of the cameras. I’ve only found them on Taobao so far. I’ve found some with the same sensor but, from what I can tell, a different pinout on Aliexpress.
