EmbedFire LubanCat is a Rockchip RK3566/RK3568 SBC family with Raspberry Pi Zero/Model B, and other form factors

As I checked out Linux 6.3 changelog earlier this morning, I noticed the EmbedFire LubanCat 2 SBC in the Rockchip section, and having never heard of the EmbedFire company or LubanCat single board computers, I decided to have a closer look.

EmbedFire is a company based in China, more exactly in DongGuan, that makes a range of LubanCat single board computers based on Rockchip RK3566 or RK3568 processors, some of which partially follow Raspberry Pi Zero or Raspberry Pi 3/4 Model B form factors, while others come with custom designs.

LubanCat 2 SBC

While the LubanCat 1 and 2 SBCs have just been added to mainline Linux (Linux 6.3), it’s unclear which features are supported in the latest kernel, but the company has a GitHub account with the Linux kernel, OpenWrt, and Ubuntu support. You’ll also find documentation in Chinese only.

I’ve just checked out the LubanCat 2 specifications in detail above, but “Dongguan EmbedFire Electronic Technology Co., Ltd” designed ten LubanCat boards, modules, and carrier boards as shown in the table below.

I would unable to find any of the boards outside of China, and some are sold on JD.com as well as Tmall with purchase links for the latter available from the products page. [Update: Lubancat SBCs and some robotics kits based on those are sold on Aliexpress]

These boards are also available at Aliexpress.
They look pretty interesting, especially RPI Zero-like ones: RK3566 on such a small PCB should offer better video streaming capabilities compared to Raspberry Pi.

In fact, there are cheaper official sales channels on Taobao.
Buying only development boards can be a bit expensive, but like 100ASK, EmbedFire will also be sold along with their teaching documents.
