"Product Description:

1. The microprocessing unit of this module is the traditional 51 kernel commonly used by us.

1, the single-chip microcomputer (STC) programming method is the same as the 51, 52 series single-chip microcomputer programming method, the user does not need to review and learn new single-chip microcomputer register, hand programming use;

2, integrated design, without tedious driver, has been developed source code, direct serial output identification code, the operation is very simple.

3, reserved 16 single-chip IO port, including a group of 8-bit IO expansion interface, 1 timer, 1 external interrupt, can be used as a single-chip microcomputer minimum system to achieve control functions, without supporting other single-chip computers to complete the work alone;

4, simplified specifications, small size, with standard 3MM fixed hole installation is easy to fix, embedded/practical;

5, with serial communication function, reserve the relevant interface, and provide 5V, 3.3V power interface, easy to download the program.

6, with password mode and ordinary pattern recognition, supporting the source program, can be developed twice.

7, the volume of 3*4.3CM is easy to be embedded in the product equipment.

8, supporting single-chip download, debugging, programming software, software with single-chip application routines, integrated timer calculation, delay calculation, serial debugging and other development tools.

"Recommended use:

1, home intelligent control

2, smart car DIY design

3. Freescale intelligent voice control

4, the major graduation design innovation function

5, personal DIY design

6, voice control embedded product design"
