Support 5V or 3.3V STC AT AVR Series MCU
Features:
1 the system board with STC and AVR double reduction operation more convenient for users to debug program;
TwoAfter the customer master 51 microcontroller further learning AVR MCU switching board only by one AVR chip you can continue to use this as a small system of AVR;
3 in the expansion of the STC microcontroller program download interface used in conjunction with the store sold STC Downloader the effect is excellent.
4.AT89S51/52 and AVR Series MCU can download download through special ISP.
5 double sided board low price only 10 yuan what are you waiting for
Baby features:
1.5V and 3.3V power supply expanding the scope of the use of SCM the company's first design customers no longer have to use the low voltage single-chip and worry!
2 with PCB double coated copper grid design green and blue two colors and some of the market is not in a single plate level;
3 single-chip 40 I/O pins all leads. Use the built-in components and SMD package design has the advantages of simple structure compact strong sense of art;
4: 11.0592M crystal
5 support chip: STC series low-voltage high-voltage AT89SXX chip and the pins and the chip compatible chip AVR microcontroller DIP-40 pin package.
6 system board either 51 or AVR series microcontroller reset double working mode.
7 can be supplied by USB by abandoning 5V power supply can save a $5-10 regulated power supply; the DuPont line can also be connected with the power supply power supply mode is optional!
8 with 2 5V and 3.3V VCC GND output convenient use of peripheral circuit;
9 has a protection diode reverse breakdown voltage components greatly improves the safety performance of the system board.
