Equipped with high-end digital isolation, effectively isolating transient high voltages up to 3000Vrms. Compatible with debuggers, including , 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 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 , the isolated power supply can be omitted and the target board can provide power to the target end. When using an isolated power supply, voltage matching; otherwise, malfunctions may occur.
