Good classroom resource

Bought ten of these for my electronics class. They are consistent in performance. One unit had a slightly loose USB port, but it still functions fine with careful handling.

Robust build quality

I've dropped this board twice and it still works perfectly. The pin headers are sturdy, making it easy to connect external modules without worrying about breaking connections.

Nostalgic and functional

Brings me back to my college days learning assembly. The 11.0592MHz crystal ensures accurate baud rates for serial communication, which is crucial for debugging.

Easy to set up on Windows 10

Installation of the CH340 driver was straightforward. The board was recognized immediately, and uploading code via the serial port took seconds. Highly recommended for university projects.

Perfect for beginners following the Bilibili course

This board matches the components used in the popular Jiang Ke Da video series exactly. The layout is clear, and the soldering quality is excellent. I had no trouble running my first 'Hello World' LED blink program.

Great value but manual could be better

The hardware is solid and all peripherals like the buzzer and sensors work as expected. The included CD has drivers, but I recommend downloading the latest datasheets online for more detailed explanations.

5 FAQ

A: The board is designed for 5V input via USB. While there is a VIN pin, we recommend sticking to the 5V USB connection to avoid damaging the regulator or chip.

Q: Where can I find the tutorial videos mentioned in the description?

A: The tutorials are available on Bilibili under the creator 'Jiang Ke Da'. The CD included also contains PDF versions of the lesson plans.

Q: Does this come with the LCD1602 screen attached?

A: No, the LCD1602 module is not pre-soldered to the board to keep shipping costs low, but the pin headers are provided so you can easily plug one in.

Q: Does this board support C language programming or only Assembly?

A: This board supports both C language (using Keil C51 compiler) and Assembly language. Most users find C easier for complex projects.

Q: Is the USB cable included in the package?

A: Yes, the kit comes with a standard Mini-USB cable for both power supply and program downloading.
