Functional Application
1. All IO ports are led out, the classic 51 minimal system saves the trouble of welding. 2. Integrated ISP 10P download interface makes it easy to download AT89S52 microcontroller. 3. The welded socket is a circular hole socket, which is convenient for replacing the crystal oscillator (default configuration is 11.0592M)& nbsp; 4. Supports chips: STC89C52 STC12C5A60S2 STC11/10x series; AT89S52 and chips compatible with the above chip pins, 5 A power switch for easy experimentation. 6. There are two ways to input power: DC-005 power socket (matching seat is 5.5 * 2.1) and single pin (next to the power switch), 7 Expand 3 VCC channels externally, GND, As shown in the needle arrangement in the figure. 8. Install a pull-up resistor on the P0 port. 9. Reset methods: power on reset and external button reset. 10. Adopting a green IC lock holder for easy chip replacement. 11. Our store independently develops and produces, with long-term stable supply. 13. Board size: 4.1cm * 8.9cm
