Product List1 x GigaDevice GD-Link V3 AdapterOther ContentBefore connection, match the target voltage with the GD32 target board. Incorrect voltage selection or pin wiring can damage the debugger and the target MCU.The official hardware overview shows the K1 button, status LEDs, buzzer, USB connector, 10-pin target connector, machine-signal connector, and voltage selection area on the GD-Link V3 Adapter.The pinout diagram maps SWDIO, SWCLK, reset, ground, UART, I2C, CAN, SPI, and one-line signals. Connect only the pins required by the target MCU interface.The output voltage can be selected for 1.8V, 3.3V, or 5V. Always verify the target GD32 board voltage before connecting the adapter.Resources Official GD-Link V3 Adapter User Guide Rev1.2 GigaDevice GD-Link downloads CMSIS-DAP documentation FAQWhich GD32 chips does the GD-Link V3 Adapter support?The official user guide states support for the full GD32 ARM and RISC-V core series.Which debug interfaces are available?The adapter supports SWD, JTAG, and OL debugging/programming interfaces.Can the adapter power the target hardware?Yes.
