8051 Microcontroller Trainer ki t circuit

Onboard buzzer reset button alone, you can do some sound tests.
Board four button inputs, selectable interrupt / query.
All four ports are connected to P pre-10K pull-up resistor row.
IIC bus support device real-time clock PCF8563.
IIC bus EEPROM board can be connected to the device 24C02, features similar to the constant strong product.
74LS244 driver chips onboard, non-simple P port directly drive, better protection against single.
MAX232 chip board, standard RS-232-C serial interface and PC can be used for onlin
