Feature:
1. The minimum system applies IT SCM STC15W4K56S4 or IAP15W4K58S4. The system is compatible with all the SCM of STC series like STC15F2K60S2.
2. The SCM applies LQFP48 , 46pcs I/O (8 pcs more than the DIP40 ), all the I/O are led out and the 2.54mm spacing layout, easy to use to the universal board ; in which the I/O P4 is designed as a standard 1602 display interface.
3. onboard the original CH340G USB turn serial chip, thus the minimum system can achieve simulation debugging, serial communication and program downloading; CH340G and the SCM can be by a jumper disconnection, that's can take CH340G as the USB serial port module, and realize the serial communication for the other target board , can also use DuPont line connecting MCU also three serial port serial communication debugging.
4. Working voltage is DC5V, program download and minimum power supply system can be accomplished by using ordinary mobile phone data line; while onboard DC3.5/1.3mm power supply socket, and can be separated by a jumper and CH340G of power supply.
5. On board power chip AMS1117-3.3V , the minimum system Vcc can switch between 3.3V and 5V.
6. The display interface can be connected to the 1602 screen, TFT display that is 1.8 Inch and OLED that is 0.96 inch .
7. Onboard WiFi ESP8266 module interface, the smallest system can access the WiFi access network or the establishment of WiFi hot spots, can use the mobile phone to the minimum system for wireless communication and control.
8. DHT11 temperature and humidity sensor /DS18B20 temperature sensor interface.
9. Onboard NTC thermistor / photosensitive resistor interface.
10. Onboard road AQY212EH optocoupler relay and the optocoupler is a two-way output, isolation drive less than 60V500mA load; as the stem node is connected to the PLC system; also can realize low frequency PWM control. At the same time can replace the series of other types of optocoupler, realize the load control of 30V ~ 600V.
11.LED*3pcs;  keybuttons*4pcs.
12. Minimum system size is 50*55mm, small and exquisite, unique and exquisite .
14. The development board uses the chip processing, quality assurance, the appearance is more beautiful.
15. IAP15W4K58S4 , the model includes RAM 4K, ROM 58K, 4 high-speed serial port, USB download program, support DC2.5~5.5V wide voltage, 6 PWM and other characteristics.

Description of STC15W4K56S4 series SCM:
- Large capacity 4096 byte on-chip RAM data memory.
- High speed: 1 clock / machine cycle,  core 8051, faster than the traditional 8051. Speed is also faster than the 1T STC series microcontroller (such as the STC12/11/10 Series) as fast as 20%.
- Voltage: 2.5~5.5V.
- Low power: low speed mode, idle mode, power down mode (which can be awakened by external interrupt or internal power wake up).
- External reset of the microcontroller is no need, ISP programming 16 reset threshold voltage optional, built-in high reliable reset circuit.
- No need for an external crystal of SCM, ISP programming internal clock from the 5MHz~35MHz can equipment of high precision R / C clock (+ 0.3%), which is equivalent to the ordinary 8051:60~420MHz.
- 16/32/40/48/56/61K Flash bytes of on-chip program memory, erasing times more than 100000 times.
- large capacity EEPROM function, endurance more than 100000 times.
- ISP/IAP, can be programmable without programmer or emulator.
- ADC with high speed , 10 channels and 8bit, the speed can reach 300 thousand times / second, 8channels PWM can also be used as 8 channels D/A.
- Comparator, which can be used as 1channel ADC, and can be used as power down detection, support external CMP+ pin CMP- and external pin to compare, can generate interrupt, also supports external tube feet + and internal reference voltage.
- 6 channels 15bits wiht dedicated and high-precision PWM (with dead time control), plus 2channels CCP, can be used to achieve D/A.
- Totally 7 timer / counter, 16 of which 5 bit to reload timer / counter.
- Programmable clock output function (clock input for the internal system clock or external clock input).
- ultra high-speed four serial /UART, four fully independent high-speed asynchronous serial communication port, the switch can be divided into 9 groups of serial port use.
- SPI high speed synchronous serial communication port.
- Hardware watchdog (WDT).
- Instruction set architecture first, compatible with the common 8051 instruction set, there are hardware multiplication / division instructions.
-  I / O port. After resetting: quasi bidirectional / weak pull ups and can be set for four kinds of modes: quasi bidirectional / weak on tension and strong push-pull / strong pull, only as output / high resistance, open drain, each I / O drive capability up to 20mA, but not of the entire chip more than 20mA.
- Provide the baud rate calculator, timer, calculator software delay calculator and a large number of examples of V program in ISP software

NOTE: I/O pin Oon the development board installed in the front, the interface of 1602 is 1*16.
