Fast and stable connection
I've tested this against more expensive alternatives and the performance is nearly identical. The I2C scanning feature in the utility software is very handy for troubleshooting sensor connections.

Perfect for embedded debugging
This board works flawlessly with my STM32 projects. The JTAG speed is impressive and the driver installation on Windows 10 was straightforward. Highly recommended for anyone needing a reliable USB-to-JTAG bridge.

Solid tool for prototyping
Works great for quick prototyping. The ability to switch between 3.3V and 5V via jumper is a nice touch. Deducting one star because the included cable is a bit short, but that's a minor issue.

Essential for my university project
Bought this for my final year embedded systems project. It handles both GPIO control and UART communication without any lag. The build quality feels solid and the pins are well-labeled.

Exceeded expectations
Very happy with this purchase. The high-speed mode actually delivers on its promise, making firmware uploads significantly faster than my old adapter. Support team was also quick to answer a question about pinout.

Great value, minor documentation gaps
The hardware quality is excellent for the price. I successfully used it for SPI flash programming. The only downside is that the example code could be more detailed for Linux users, but community forums helped fill the gaps.
Q: Does the package include the connecting cables?
A: Yes, the package includes one USB Type-C to Type-A cable and a set of Dupont jumper wires for connecting to your target board headers.
Q: Can I use this to program ESP32 modules?
A: While the ESP32 typically uses UART for flashing, this board can handle the UART interface required. However, for JTAG debugging on ESP32, ensure your specific module exposes the necessary JTAG pins.
Q: Does this board support SWD debugging for ARM Cortex-M processors?
A: Yes, the CH347T/CH347F supports SWD (Serial Wire Debug) protocol which is compatible with most ARM Cortex-M microcontrollers including STM32 and GD32 series.
Q: What is the maximum current this board can supply to the target device?
A: The board can provide up to 500mA via the VOUT pin when powered by a standard USB port. We recommend using an external power source for targets requiring higher current to ensure stability.
Q: Is there a driver available for macOS Monterey?
A: Yes, WCH provides official drivers for macOS including Monterey and later versions. You can download them directly from the manufacturer's website under the CH347 product page.
