Description:
The WT588D-U-32M Voice Module is a digital recording and playback device. It can operate as a standalone playback device, or it can be controlled by a microprocessor such as an Arduino.
The DC2.8V-5.5V Mini USB Interface Sound Module exists in several formats; the -U shows that the board has a USB to allow uploading sound files. The memory storage is shown by 32M (32 MB) and there are also 16 MB versions.
Specifications:
- Supply Voltage: DC 2.8V 5.5V
- Application: Computer
- Dissipation Power: WT588D-20SS WT588D 20SS

Features:
- Package of 28-pin modules, which can be replaced with memory for gaining different lengths of storage time.
- Supports 2M bit ~ 32M bit capacity SPI-Flash (Note: 1 byte = 8 bits)
- The WT588D-20SS voice is used as a control core chip.
- Embedded human voice processor, feels very natural and sweet.
- Good audio quality output for 13-bit/DA converter and 12-bit/PWM processing of audio. Support for loading 6K ~ 22K Hz audio sampling rate.
- PWM output can directly promote 0.5W/8 speakers and plenty of current.
- Support DAC / PWM output.
- Support for loading WAV audio format.
- Support key control mode, one-wire serial control mode, and three-wire serial control mode.
- A variety of IO trigger ways can be set to button control mode.
- The way BUSY signal output can be set randomly.
- Loading no more than 500 segments of voice for editing.
- The address bit is controlled by 220 segments of voice, but a single address bit can just load up to 128.
- Voice player to enter the sleep mode to stop immediately.
- It is a simple interface and convenient because of using the WT588D Voice Chip that benefits from exerting its functions.
- A lot of operations can be finished in software. Such as setting up control mode, inserting voice, composing voice, calling voice, etc.
- Support online USB download / offline USB download? Moreover, it also can download data to SPI-Flash even if WT588D-U is working.
- Dormant current less than 10uA
- Powerful anti-jamming. Widely used in the industrial field.
