Tiny but powerful
Impressed by how much functionality is packed into such a small board. The GPIO pins are easy to access, and the 3.3V logic level is perfect for modern sensors.

Good hardware, sparse docs
The hardware quality is solid and the chip runs stable at 24MHz. However, you need to dig around online for English documentation and example code. Once set up, it works great.

Perfect for 8051 learning
This board is exactly what I needed to get back into 8051 development. The USB programming works flawlessly on Windows without needing an external programmer. Great value for the price.

Great bulk buy for workshops
Bought ten of these for our weekend workshop. Most worked out of the box. One had a slightly loose USB port, but overall a reliable choice for teaching basics.

Excellent for university projects
Used this for my embedded systems final project. The built-in USB bootloader makes uploading code incredibly fast. Highly recommend for students on a budget.

Fast shipping and genuine chip
Arrived quickly and packaging was secure. Verified the chip ID using the official tool, and it is indeed a genuine CH552T. No issues with compilation or flashing.
Q: Is there a reset button on the board?
A: Yes, there is a physical reset button included on the PCB to easily restart your program without disconnecting the power or USB cable.
Q: Does this board support Arduino IDE?
A: No, this board uses the 8051 architecture and requires specific compilers like SDCC or the official WCH compiler. It is not compatible with the standard Arduino IDE which targets AVR or ARM chips.
Q: Does it come with a USB cable?
A: Typically, the board is sold without a USB cable. Please ensure you have a micro-USB data cable available to connect the board to your computer for programming and power.
Q: Can I power this board via the USB port alone?
A: Yes, the board can be powered directly through the micro-USB connection when connected to a computer or a standard 5V USB charger. The onboard regulator handles the conversion to 3.3V.
Q: What operating systems are supported for programming?
A: The programming tool is primarily designed for Windows. Some users have reported success running the tools on Linux using Wine, but native macOS support is limited.
