Robust for Industrial Control Learning
Used this to prototype a simple motor controller logic. The interrupt handling is precise, and the timer modules work exactly as documented in the datasheet. Highly recommended for educational purposes.

Good for bulk orders
Purchased 10 units for our club. Consistency across all boards is high. The only reason for 4 stars is that the USB cable could be a bit longer, but that's a minor complaint.

Classic Design, Reliable Performance
The Puzhong Classic series never disappoints. The build quality is solid, and the pin headers are well-soldered. It's an ideal platform for students transitioning from simulation to real hardware.

Great value, minor LED brightness issue
Overall an excellent board for learning C51 assembly and C programming. All peripherals work as expected. One of the segment display LEDs was slightly dimmer than the others, but it doesn't affect functionality.

Easy to get started
I was worried about setting up the environment, but the included resources and the standard STC ISP software made it incredibly easy. Blinking an LED took me less than 10 minutes.

Perfect for University Projects
Bought this for my automation class at Jiangke University. The layout is very clear, and the schematic matches the textbook examples perfectly. The USB download feature works flawlessly on Windows 10.
Q: Does this board come with the USB downloader cable?
A: Yes, the package includes a USB to TTL serial cable specifically configured for STC microcontrollers, allowing you to program the chip directly without an external programmer.
Q: Are there example codes available for the 7-segment display?
A: Yes, upon purchase, you will receive a link to our resource repository containing sample code in both C and Assembly for all onboard modules, including the 2-digit 7-segment display, keys, and buzzer.
Q: Is this compatible with Keil uVision software?
A: Absolutely. This board uses the standard 8051 architecture, making it fully compatible with Keil uVision, SDCC, and other popular compilers for C51 development.
Q: What specific MCU model is pre-installed?
A: The board typically comes with the STC89C52RC pre-installed, which is a high-performance CMOS 8-bit microcontroller with 8K bytes of In-System Programmable Flash.
Q: Can I power this board with a 9V battery?
A: The board is designed primarily for 5V USB power. While there is a VIN pin, we recommend sticking to the 5V USB input to ensure stable operation of the onboard peripherals and to avoid damaging the voltage regulator.
