summary:
WT2003HB01 is a powerful high-quality product Voice module High performance 32-bit processor is adopted, and the maximum frequency can reach 120MHz. It has the characteristics of low cost, low power consumption, high reliability, and strong versatility. It can have a built-in voice capacity of 100 seconds 350 seconds. Flexible control mode: support standard asynchronous serial port communication (UART). SPI Flash and USB flash disk are supported as storage. It has the functions of file index play, insert, single track cycle, all track cycle, random play, etc. The 32 level volume is adjustable, and can support 128 Mbit Flash and 32G USB flash disk.
Product features:
(1) Support SPI Flash and USB flash disk;
(2) Support FAT, FAT32 file system;
(3) Control mode: standard UART communication interface, support DMA and flow control, default baud rate 9600 ；
(4) Power on does not play by default; With BUSY status indication, it is high level when BUSY is playing;
(5) Support switching audio output mode, sample default SPK output, if DAC output is required, Please refer to the audio output switching command (0xB6);
（6） The external Flash can be connected to the computer through the USB interface of the module to view or modify its contents, and the voice in the computer can be directly downloaded to the removable flash simulation drive (analog U disk) (XP system, WIN7 system, WIN10 system);
(7) Support high-quality voice audio format, (8kbps~320kbps) beautiful voice;
(8) Working voltage: 2.4-5.2V;
(9) It can support 128 Mbit Flash and 32G USB flash disk (FAT or FAT32 format) at most;
(10) Built in 0.5W Class D power amplifier;
(11) The volume is adjustable, and the volume level is 32;
(12) Two 16 bit asynchronous frequency divider timers;
(13) Digital audio stream, IIS supports host and slave modes;
(14) One IIC controller
(15) An infrared remote control decoder;
(16) 16 bit high-precision ADC;
(17) 16 bit high-precision DAC;
(18) High power IO drive capability, up to 64mA can be directly driven;
（19） When using a single module (using the built-in capacity), the built-in voice needs to be written before leaving the factory.
（20） Connect the computer through the USB interface, and the flash or TF card drive letter is displayed on the computer. Copy the audio directly from the computer to the drive letter. After the copy is completed, unplug the USB cable, and then play through the serial port control, otherwise the serial port sends code without response;
（21） Support SD card/USB flash disk offline upgrade program. It is recommended to reserve an interface when drawing board ；
If the voice chip needs flash. Flash produced by "Weichuang" must be used. If it is not used for special reasons, it must be handed over to our company and noted. (It will not work because you use the flash of other home without permission)
