51 MCU Development Board / 51 Minimum System Board / STC89C52 / Smart Car Control Panel

51 MCU development board / 51 Minimum system board / STC89C52 / smart car control panel This system board has the following advantages: Download: USB download (you can download the SCM STC) and 12-pin download way (you can download the AT89S1, AT89S52 Series MCU). 2, power supply: USB power supply, and an external power supply (external power supply in the power supply voltage of 5V power supply). 3,8 Road LED indicator (to know the importance of the LED indicator With this indicator can direct light indicates the working status of the program, to facilitate debugging actually works better than the emulator Oh. The microcontroller crystal pluggable be replaced at any size, suitable for different applications and experiments occasions. 5, power supply 5V and GND leads through the vent needle, convenient to expand outside the circuit of the power of the incoming and outgoing convenient circuit Billiton. DS18B20 temperature sensor interface, you can do temperature measurement experiment, this price does not include the DS18B20 Oh, if needed another shot. 7, infrared integration receiving head, can fit any infrared remote control experiments, this price is not including the integration receiving head, then need another shoot. 8, four digital tube can do digital tube display experiment. 9, four separate buttons, you can do key experiments. 10, the buzzer can be used for voice alarm experiments 11,1602 LCD circuit interface, you can do experiments on LCD. The 12,12864 LCD experiment, 12,864 LCD can do experiments. 13, an increase of the module interface for wireless serial experiments 14, steering gear with infrared photoelectric switch interface, you can control the steering gear, infrared obstacle avoidance sensor 15, P1 port pluggable jumper with STC12C5A60S2 can be used as the input of the AD converter, PWM output, very convenient!
