FN-M22P may be a high-quality audio playback module, which integrates MP3 and WAV decoder together perfectly, and supports parallel interface control mode, UART interface control and key control mode. It takes an SD card or USB flash stick because the memory device , which may be chosen by users freely. It are often controlled easily via MCU commands or external push-buttons. Easy to work and high performance.This embedded MP3 module is an universal and compact circuit (37 mm x 27 mm) for enjoying MP3 audio files. The MP3 module are often utilized in embedded systems.
The MP3 files (up 65,536) are stored during a micro SDcard. The module are often wont to play voice messages in vending machines, telephone systems, within the car to tell the driving force of the vehicle’s condition and environmental ones, in alarm systems, to help configuration and inform about events that occurred, and in many other areas yet. The device supports micro SD with capacity up to 16 GB and may be powered with a voltage of three .3 Vdc or 5 Vdc selectable. The module features a single in-line single-connector positioned on one side of the PCB, so you'll better manage the space and mount it also in upright position.
Controlling the module might be done either by buttons and digital inputs or via TTL serial interfaces.
Its features involve: With high-quality audio decoder, supports MP3 and WAV audio formats.
Sampling rates supported: 8/11.025/12/16/22.05/24/32/44.1/48(kHz), 24 bit DAC output and supports dynamic range 90dB and SNR 85dB. Supports key control mode, parallel control mode and UART interface control mode. Possible to update audio files in the SD card via the USB connecting with the PC. Supports a maximum of 3000 audio files under the root directory of the storage device. Supports a maximum of 99 folders and each folder stores maximum of 255 audio files.
