Embedded systems, control, power, and motor drives嵌入式、控制、电源与电驱

This is Alvin Li. I develop embedded systems across hardware and firmware. I draw schematics, lay out PCBs, write firmware, and handle board bring-up, hardware-software integration, and bench validation.这里是 Alvin Li，主要做嵌入式软硬件全栈开发。平时会画原理图、布 PCB、写固件，也会做板级调试、软硬件联调和台架验证。
