A direct connection to the work.

Yanju Electronics is operated by Yiwu Yanju Electronic Products Firm, based in Yiwu, China. Engineering work is led by Shunxin Zhang, whose background is in hardware development, board debugging and hardware–firmware integration.

Our five services cover custom electronic product development, schematic and PCB design, embedded development, design review and debugging, and prototyping and manufacturing support. Projects begin with the problem you need to solve and a clearly agreed scope.

PCB fabrication, component sourcing and assembly are coordinated with production partners. The manufacturing plan and responsibilities are confirmed for each build.
