根据STM32硬件开发文档绘制，原理图与PCB齐全，所使用的原理图库和PCB库也已配齐。经本人测试，完全可用，ISP系在和JLINK下载仿真都已实现。-According to the document drawn STM32 hardware development, schematics and PCB complete, the use of schematic library and PCB libraries have also been installed for. I tested

传统20脚JTAG底座个头大，占用PCB面积多，连接线复杂。基于STM32F103C8T的SW模式Jlink，只需要三根线即可与目标板实现通讯，可实现程序下载，单步调试等功能，除了不能检测目标板电压、不能给目标板供电、速度有所降低之外，与完整版JLink的功能是一样的。当然，成本也可以降低很多(The traditional 20 foot JTAG base is large, occupies more PCB area, and has complex connection line. J
