Mini vibration engine for Arduino and Raspberry Pi 5 VDC

Reprogrammable voice module with large storage capacity that can support the maximum 1GB SD card, and support audio files of WAV and ad4 format.
Wtv020-sd module uses wtv020sd-20s Voice chip as master core, with MP3 control mode, one to one key control mode (control 3 voice groups or 5 voice groups), 2-wire serial port control mode and loop play mode after power on. Control mode is set by programming the voice chip, and can't change to another control mode during operation, what control mode do you need, just tell us, we can customize it for you.
