I'm proud to share my latest High speed PCB,

and the Second Board of my custom SBCs.

Link for my First SBC.

Assembly video at my house.

And this is a video for testing.

*SBC_RK3576_V1.0

A fully custom-designed Single Board Computer based on the Rockchip RK3576,

built from scratch – schematics, layout.

The board is designed for industrial use,

AI applications, and advanced embedded applications.

Big thanks to PCBWay for sponsoring this project!
