Perfect for learning 8051 assembly
The ZIF socket makes swapping chips incredibly easy when testing different code versions. The board is well-labeled and the silk screen is clear. Great value for students.

Exactly what my university lab uses
Bought this to practice at home. It matches the specs of the boards we use in class. The 11.0592MHz crystal ensures accurate baud rates for serial communication.

Good classroom resource
Ordered ten of these for my electronics club. They are durable enough for beginner handling. One board had a slightly loose USB connector, but power via the jack works fine.

Solid build, minor soldering needed
The board arrived in good condition. You need to solder the pin headers yourself, which is fine for this price point. The reset button feels a bit stiff but works reliably.

Great for vintage computing projects
I'm using this to interface with some old LCD displays. The 5V logic level is perfect, and having all pins accessible via headers saves a lot of time.

Reliable and affordable
No issues with the STC core. Flashing new firmware is quick. The ZIF socket is the highlight here; it prevents bending pins on the microcontroller during frequent changes.
Q: What programmer do I need to upload code to this board?
A: You will need a standard USB-to-TTL serial adapter (like CH340 or CP2102) connected to the TX, RX, GND, and VCC pins, along with the STC-ISP software.
Q: Does this board come with the STC microcontroller chip pre-installed?
A: Yes, the board typically comes with an STC89C52RC chip installed in the ZIF socket, ready for programming.
Q: Can I power this board directly from a 9V battery?
A: Yes, you can connect a 9V battery to the DC power jack or the designated VIN pins, as the board includes a voltage regulator to step it down to 5V.
Q: Are the pinouts compatible with standard 40-pin DIP sockets?
A: Absolutely. The board follows the standard 8051 40-pin DIP layout, making it compatible with most existing shields or breadboard setups designed for this architecture.
Q: Is the source code for the demo program included?
A: A basic blink example hex file is often pre-loaded. Full source code examples in C and Assembly can be downloaded from our support page or the manufacturer's website.
