Reasons for purchasing 51 development board


1. By default, a USB cable can be used for power supply and download. There is a ch340 serial communication download chip on the board, which can be directly downloaded by STC single-chip . At the same time, if the AT series single-chip is used, the development board has an ISP download interface, which can be directly connected to the ISP downloader for downloading.


2. The development board adopts 40p IC lock seat, which is convenient for chip replacement. By default, it comes with STC89C52RC, you can replace the chip with the same pin of this chip, such as STC system pin compatible chip; AT89S51, AT89S52; ATmega16, ATmega32 (AVR need to cooperate with 51 / AVR adapter board)


3. The key part has jumper cap, which can be disconnected to make it independent unit


4. development board power supply mode: computer USB power supply (USB interface) and external 5V power supply (dc-005 power supply).


5. development board reset mode: power on reset and 51 / AVR double key reset;


6. development board crystal oscillator: adopt round hole socket welding method, convenient for users to replace crystal oscillator


7. external expansion power supply: 3-way 5V power supply is expanded through the row of pins to facilitate the connection of external experiment;


All IO pins are expanded to facilitate the connection of external experiments;
 
Driver and development environment
1. Driver support: WINDOWS 98 / ME / 2000 / XP / Server 2003 / VISTA /
Server 2008 / Win7 / Win8 32 Bit / 64/Win10
2. Development environment:Keil
3. Downloard: STC-ISP


As shown in figure 1 welding good 51 development board piece (including the copper column)
2 STC89C52 microcontroller (industrial) a chip
3 download the power cord a USB power supply (download and power supply for the same power cord)
