ITEM NAME:Speech Recognition Module Voice Board Vrm Ld3320 Asr 5V Power 43 X 29.7Mm V6Y8 Speech Recognition Module Voice Board Vrm Ld3320 Asr 5V Power 43 X 29.7Mm V6Y8 Supply voltage: 5V IO port output: 3.3V High level Communication: Serial communication 1, The microcontroller (STC) programming mode is the same with 51, 52 series microcontroller programming mode, users do not need to re-learn a new microcontroller register, it can be programmed directly; 2, Integrated design, eliminating the tedious drive, has been supporting the development of source code, direct serial output identification code, the operation is extremely simple. 3, Set aside 16 single-chip IO port, including a group of eight IO expansion interface, a timer, an external interrupt, can be the smallest single-chip system control functions, without supporting with other MCU to complete the work; 4, Small size, easy mounting and embedding is very practical; 5, With the serial communication function, set aside the relevant interface and provides 5V, 3.3V power supply interface for easy download. 6, With the password mode and normal mode of identification, come with source code, can be secondary development.. 7,easily embedded into the product device. Communication: Serial communication (3.3v TTL level,, does not support max232, RS485) SCM parameters: Model -> STC11L08XE, flash -> 8k, SRAM -> 1280, eeprom -> 32k Use recommended: 1, Home intelligent control 2, Smart car DIY design 3, Freescale intelligent voice control 4, Personal DIY design 5, Voice control of embedded product design colour:blue Material:Plastic + metal size:Specifications: 43 x 29.7mm Mounting hole: 3 mm Volume:3 * 4.3CM Package Contents: 1 * Speech Recognition Module 1 * USB to TTL downloader 1 * DuPont line
