Excellent for university projects
Bought this for my embedded systems course. It handles all the basic GPIO and timer tasks without any issues. The documentation online is sufficient to get up and running quickly.

Perfect for learning 8051 architecture
This board is exactly what I needed to get started with the STC15 series. The pinout is clearly marked, and it works flawlessly with the STC-ISP software. Great value for the price.

Good quality, small form factor
The soldering quality is excellent. It's very compact, which is great for embedding in small projects. Only downside is that you need a USB-to-TTL adapter separately for programming.

Reliable and stable
We use these in our workshop for teaching microcontroller basics. They are robust and haven't failed us yet. The internal oscillator is accurate enough for most learning applications.

Fast shipping and good product
Arrived well-packaged. The chip is pre-soldered correctly. I was able to blink an LED within 10 minutes of unboxing. Highly recommended for beginners.

Great starter board
Very easy to set up. The minimum system design means less clutter on the breadboard. Would recommend buying a few spares as they are quite affordable.
Q: Is the crystal oscillator external or internal?
A: This specific model utilizes the high-precision internal clock, so no external crystal oscillator is required for basic operation.
Q: What software is required to upload code to this board?
A: You can use the official STC-ISP software, which is available for Windows. It supports downloading code via the UART interface.
Q: Can this run at 3.3V logic levels?
A: Yes, the STC15W204S supports a wide voltage range from 3.3V to 5.5V, making it compatible with both 3.3V and 5V logic systems.
Q: Does this board come with a USB cable for programming?
A: No, this is a minimum system board. You will need a separate USB-to-TTL serial adapter to program the microcontroller.
Q: How many GPIO pins are available on the SOP8 package?
A: The SOP8 package provides 6 general-purpose I/O pins, as two pins are reserved for VCC and GND, and two for UART programming.
