It’s always interesting to look into mainline Linux changelog either to find out about new software features, but also new hardware platform. And earlier today, I wrote about Linux 5.4 release, I noticed comments about “Leez RK3399 P710 SBC“.
After searching a bit, it turns out it’s a single board computer by Lenovo, which the company apparently showcased at World Mobile Congress in Spain last February. Leez is apparently a team part of Lenovo.

There’s very little info on Lenovo website, which also lists another board – Leez P515 – powered by a Texas Instruments Sitara processor. But we get many more details on Github at least for Leez P710 board. That’s where I got more detailed specifications, and we can find the firmware files and tools for the SBC such as Android 7.1 & 9.0, as well as Debian. Schematics and other resources are also available on that page.
The board may target the Chinese market, but I could also notice it for sale on Aliexpress for about $140 shipped, including heatsink and WiFi antenna. You’ll also find bundles with various accessories including a debug board, camera module, 4G module, or 10.1″ touch screen display.
