tip

VREF B Requires power from the target board, voltage range 2.5V to 5.5V, Power Debugger IO voltage set to 3.3V or 5V, Serial port isolated, need to be accessed from the green independent 4PIN.

3：PW200/PW300​

Supported protocols: UART, SWJ, SWIM, ITM(SWO), wiring diagrams are referenced below:

image-20240116165101421

tip

VREF B Requires power from the target board in the range of 2.5V to 5.5V, with the PowerWriter® IO voltage set to 3.3V or 5V (no external reference can be set).

4：PW400​

Supported protocols: UART, JTAG, wiring diagrams are referenced below:

image-20240116165241568

tip

VREF B Requires power from the target board in the range of 2.5V to 5.5V, with the PowerWriter® IO voltage set to 3.3V or 5V (no external reference can be set).

caution

GND to L needs to be adjusted (see Change for PW400).

5：PWX1​

Supported protocols: UART, JTAG, SWJ, PWM, SWIM, wiring diagrams are referenced below:

image-20240116165551535

tip

VREF B needs to be powered from the target board with a voltage range of 2.5V to 5.5V with the PowerWriter® VREF voltage set to 3.3V or 5V (no external reference can be set).

tip

If you need to write STM8, you should short the green resistor bit as shown (see Short for SWIM).
