Ld3320 Speech Recognition Module Development Board With Da Converter Microphone Audio Output Speake

The programming of the single chip microcomputer (STC) is the same as of the 51 and 52 series single chip muscle programming . The user does not need to re-check and learn the new single-chip register, and can program and use it;Integrated design, eliminating the need for cumbersome drivers, supporting development of source code, direct serial output identification code, the operation is extremely simple.16 MCU O ports are reserved, including a set of 8-bit O expansion interface, 1 timer, and 1 external interrupt, which can be used as the smallest system of MCU to realize control function, without supporting other MCUs to complete the work aloneSimplified specification, volume standard, M holes for easy installation and fixation, strong embedding/practicality It has serial communication function, reserved relevant interfaces, and provides 5 and 33V supply interfaces to facilitate downloading programs.It has password mode and common mode recognition mode, supporting source program, and can be developed twice. The volume of 3x43CM is easy to embed into the product equipment. Software for downloading, debugging, and programming of MCUSupply voltage: 5VI0 port output: high level 3.3VCommunication : serial communication (33VTTL level, does not support max232, RS485)Suitable intelligent control, intelligent car design, Freescale intelligent voice control, innovative functions of major graduation , personal design, voice control embedded product design, compatible with 51, , STM32 Raspberry series Colour:blueMaterial:ABS+MetalSize:43 x 29.7MM Package Contents:1 x speech recognition module4 x female-to-female wires1 x USB to TTL cableOnly the above package content, other products are not included.Note: Light and different displays may the color of the item in the a little different from the real thing.
