WT2003HM04 Module Specification
■WT2003HM04 is a powerful high-quality voice module with a high-performance 32-bit processor, capable of reaching a maximum frequency of 120MHz. It features low cost, low power consumption, high reliability, and strong versatility, with a built-in voice capacity of 900 seconds. The control methods are flexible: it supports UART Control Mode; it supports One-line Serial Port and Two-wire Serial Control Mode; it also supports button control mode (button control mode requires micro customization). Each control mode is fixed before leaving the factory, and samples need to be confirmed with our business personnel first.
●Product Features
■UART Control Mode: Standard UART communication interface, default baud rate 9600; supports SPI-Flash as storage. Functions include file index playback, interstitial playback, single track loop, all track loop, random playback, etc. 32-level adjustable volume, maximum support for external 128Mbit Flash.
■Single Wire Serial Control Mode: Voice playback, stop, loop playback, and volume control can be controlled through the code transmission end; 8-level adjustable volume, supports SPI-Flash as storage: maximum support for external 128Mbit Flash.
■Two-wire Serial Control Mode: Voice playback, stop, loop playback, and volume control can be controlled through the code transmission end; 8-level adjustable volume, supports SPI-Flash as storage: maximum support for external 128Mbit Flash.
■Button Control Mode: Flexible trigger modes, can set any key as pulse repeat trigger, pulse non-repeat trigger, invalid key, level hold non-loop, level hold loop, non-hold loop, previous track non-loop, next track non-loop, previous track loop, next track loop, volume+, volume-, play/pause, stop, play/stop, etc., a total of 15 trigger modes, up to 10 keys can be used to trigger control output.
■Default no playback after power on; with BUSY status indication, BUSY is normally low level, high level during playback.
■Supports switching audio output modes, sample defaults to SPK output, for DAC output, please refer to the audio output switch command.
■Supports high-quality audio formats, supports MP3 and WAV formats, (audio bit rate supports 8kbps~320kbps) with beautiful sound.
■Operating voltage: 2.4-5.2V.
■Built-in 0.5W D-class amplifier.
■Two 16-bit asynchronous divider timers.
■Digital audio stream, IIS supports host and slave modes.
■One infrared remote control decoder.
■16-bit high-precision ADC and DAC.
■High-power IO driving capability, up to 64mA.
■Single-chip use (built-in capacity) requires pre-writing of built-in voice before leaving the factory.
■Supports UART update program and voice, it is recommended to reserve UART serial port when drawing board, please refer to the serial port upgrade document for upgrade.
■M04 module is not burned with the project, before shipment, it is necessary to confirm the burning project version, please refer to the following Selection Table for details.
■Supports SD card/U disk offline upgrade program, it is recommended to reserve interface when drawing board.
■If the voice chip needs to be mounted with flash, it must use the flash provided by "Waytronic". If it is not used for special reasons, it must be handed over to our business, and it must be noted. (Because using flash from other companies without permission will cause it to not work).
