I Configuration in board
Standard configuration is PIC18F4520, user can change to other DIP40 packaged PIC MCUs by themselves, alternative model: PIC16F874A, PIC16F877A, PIC16F74, PIC16F77, PIC16F747, PIC16F777, PIC16F884, PIC16F887, PIC16F914, PIC16F917, PIC18F442, PIC18F452, PIC18F448, PIC18F458, PIC18F4420, PIC18F4455, PIC18F4550, PIC18F4585, PIC18F4680, etc 19 kinds of models LED: 8 LEDs with green paster, can conduct light water experiment and so on Nixie tube:
1 bit red nixie tube, at the first stage of studying nixie tube, this one is the most ideal one, and it is most easy to master principle.
4 bits red nixie tube, after you learned static status display, you can use this one to learn dynamic display 4 bits digit LED dot matrix:
4 8×8LED dot matrix, it makes up 16×16 matrix screen, only the 16 dot matrix can display character.
1602 LCD port: 1602 LCD port, it can be inserted into this LCD module to conduct character display experiment
12864 LCD port: 12864 LCD port, it can be inserted into this LCD module to conduct character, figure and anime display experiment (note: The LCD is provided for oneself)
Storage:
It adopts AT24C02
RTC (real-time clock): It consists of PCF8563, crystal oscillator (32768Hz) and backup battery holder
A/D (analog-digital conversion): It consists of potentiometer and switching jumper, by switching jumper, it can conduct experiment to all 8 analog input port of MCU
RS232 serial interface: Onboard RS232 interface circuit, it can be easy to conduct communication experiment with serial port debugging assistant
Temperature sensor: It consists of DS18B20 and switching jumper, by Dupont cable, it can be connected on any IO port. It can conduct temperature display and control experiment.
PS/2 keyboard interface: It can be connected to any PS/2 port, it can conduct keyboard decode experiment
Relay and its contactor: The NO contactor of relay can be brought out by detachable terminal, and it can conduct control experiment of heavy current installation
Infrared receiver: Onboard 38 KHz infrared integration receive end, it can conduct decode experiment for IR remote signal
8 independent keys: 8 pieces independent keys, it is equipped with pull-up resistor for each key, it can conduct key input and MCU external pin interrupt experiment. 4×4 matrix key: 16 pieces keys make up 4×4 matrix, it has pull-up resistor, and it can conduct key input experiment
Stepping motor port: It is suitable for matched stepping motor, and it can conduct control experiment of stepping motor.
74HC595 unit circuit: It consists of 2 pieces 74HC595 chips and input output pins, it can conduct drive with hardware SPI of MCU to do serial-parallel experiment, the 2 pieces 74HC595 adopt cascade system connection, it has practical value for the project that requires extension due to a large number of output port demand.
Crystal oscillator: It takes socket method, it is easy for users to change crystal oscillator by themselves, standard 4M
Reset button: Press reset button at any time, MCU get reset, scientific design, even if press suddenly when programming or simulating, it will not damage the programming unit and simulator, for the developing board without this design, if press reset button suddenly, it will damage the device.
Programming, simulating ICSP port: Standard 6 pins ICSP programming, simulate port, it can conduct simulation or program writing for onboard MCU Standard 5 pins ICSP programming, simulate port, it can conduct simulation or program writing for onboard MCU II Configuration outside the board
1602 LCD module:
Yellow backlight, after pin finished welding, it can be directly used after inserting on developing board
Stepping motor:
DC5V, five-wire four-phase, it can be directly used after inserting on developing board.
IR remote control
Adopted chip: HT6221, containing butteries
PP2011 programming unit:
USB port, no drive running, it supports many kinds of operating system, it can conduct program download for onboard MCU.
