Equipped with high-end digital isolation, effectively isolating transient high voltages up to 3000Vrms. Compatible with various debuggers, including JLink, STLink, DAPLink, etc. Dual isolation for signal and power, surge protection, and anti-static protection. Suitable for debugging high-voltage target boards such as motors, industrial control boards, and battery protection boards. This product requires pin 2 of the debugger's JTAG interface to power the isolation board; otherwise, it will not function. The chip's built-in isolated power supply module provides power to subsequent stages. The 3.3V/5V supply voltage is selectable via a DIP switch (maximum current 100mA). High-speed debugging is unrestricted, supporting download speeds up to 9.6Mbps. *Note: Slight variations in the output voltage of the isolated power supply are normal. If voltage requirements are very strict, the isolated power supply can be omitted and the target board can provide power to the target end. When using an isolated power supply, ensure voltage matching; otherwise, malfunctions may occur. Color: Black Material: plastic Package Contents: 1* SWD High Voltage Isolation Board
