DESCRPIPTION AND FEATURES

51 Single-Chip Microcomputer System Board

Product Features

IO ports are led out, and the 51 minimum system eliminates the trouble of welding.
Integrates an ISP 10P download interface, facilitating the download for AT89S52 single-chip microcomputers.
Round-hole sockets are used for welding, making it easy to replace the crystal oscillator (11.0592M is provided by default).
Supported chips: STC89C52, STC12C5A60S2, STC11/10x series, AT89S52, and chips pin-compatible with the aforementioned ones.
Power switch + indicator light. A power switch is convenient for experiments, and there is an indicator light.
Two power input methods: DC-005 power socket (the matching socket is 5.5*2.1) and single-row pin (next to the power switch).
Three external VCC and GND circuits, as shown by the pin headers in the figure.
Pull-up resistors for P0 port.
Reset methods: power-on reset and external key reset.
Green IC lock sockets are adopted, making chip replacement easy. The movable locking sockets are convenient for frequent plugging and unplugging during experiments.
Board size: 41mm*89mm

Working Modes

Power – down mode: Typical power consumption < 0.1 μA. It can be awakened by an external interrupt. After the interrupt returns, the original program continues to execute.
Idle mode: Typical power consumption is 2 mA.
Normal working mode: Typical power consumption is 4 mA – 4 mA.

The power – down mode can be awakened by an external interrupt and is suitable for battery – powered systems such as water meters and gas meters, as well as portable devices.

Application

Education:Widely used in universities and training institutes for teaching embedded system fundamentals, as the 51 single chip microcomputer is easy to understand for beginners.
Home Automation:Controlling simple devices like lights, fans, and small robotic systems. For example, a 51 mcu development board with Stc89c52rc can be used to build a system that turns on lights at a specific time.
Industrial Control:Basic monitoring and control tasks where high – end controllers like Stm32 are not necessary, such as simple sensor data logging (temperature, humidity sensors connected via I/O ports).
Hobbyist Projects:Enthusiasts use 51 MCU and Stc89c52rc for building robots, remote – controlled cars, and DIY electronic gadgets.
