Essential for IoT development
Bought this for developing ESP32 and STM32 projects. The multi-protocol support means I only need one dongle on my desk now. Driver stability has been perfect over three weeks of heavy use.

Great value but docs could be better
Hardware quality is excellent and the Type-C connector is a nice touch. The driver installation on Windows was smooth. However, the example code for the GPIO mode was a bit sparse, required some digging in the datasheet.

Perfect for embedded debugging
This board replaced my old FTDI adapter instantly. The JTAG support works flawlessly with OpenOCD, and the SPI speed is impressive for flashing external memory chips. Highly recommended for firmware engineers.

Solid performer
Works exactly as described. The voltage selection jumper is clearly labeled. Only minor issue is that the LED indicators are quite bright at night, but that's a trivial complaint for such a capable tool.

Fastest USB-to-UART I've used
The 6Mbps baud rate is not a joke; it makes log dumping significantly faster than standard 115200 or even 921600 adapters. The I2C scanner utility provided by WCH worked immediately on my Linux box.

Swiss Army knife for makers
I love that I can switch between UART, SPI, and I2C without changing hardware. It's become my go-to tool for testing sensors and modules. The build quality feels very solid for the price point.
Q: Can I use this to program AVR microcontrollers via ISP?
A: Yes, by configuring the chip in SPI mode, you can use it with avrdude to program AVR devices, though you may need to adapt the pinout connections manually.
Q: Does this board support 1.8V logic levels directly?
A: No, the board operates at 3.3V or 5V selectable via jumper. For 1.8V devices, you will need an external level shifter.
Q: What is the maximum current the 3.3V output can supply?
A: The onboard regulator can supply up to 500mA, which is sufficient for most low-power debugging tasks and small peripheral modules.
Q: Does it work with macOS M1/M2 chips?
A: Yes, WCH has released native drivers for Apple Silicon. Ensure you download the latest driver version from the official website for best compatibility.
Q: Is there a Python library available to control the GPIO pins?
A: Yes, WCH provides a C SDK, and there are several community-maintained Python wrappers available on GitHub that utilize the underlying DLLs for GPIO control.
