    A kind of SWD & JTAG Isolater

    Hi, I designed a kind of SWD & JTAG Isolater for Jlink & STLINK, for online debugging. This may keep person and PC USB port from PCB board burning. Can be used in Motor Control, Digital Power and some high-voltage applications. IDE: Keil, IAR, Jflash, STM32 ST-LINK Utility; SWD: 2MHz; JTAG: 6MHz;
