Module phát nhạc MP3 WAV microUSB chip nhớ JQ8900
Module phát nhạc nhỏ gọn với kích thước 18x20mm với nhiều tính năng chắc chắn sẽ là lựa chọn hàng đầu cho các bạn khi thiết kế một project cần phát nhạc, giọng nói.
Module phát nhạc này có khả năng phát trực tiếp file WAV và file MP3. Với chip nhớ trang bị sẵn và giao tiếp USB tích hợp, tất cả việc cần làm của chúng ta là:
- Cắm module vào máy tính qua cổng MicroUSB - copy file âm thanh vào 'ổ USB" - ra lệnh phát nhạc.
Module tích hợp mạch khuếch đại âm thanh nên ta có thể đấu trực tiếp loa vào và sử dụng. Giao tiếp với module thông qua UART hoặc one-wire.
Đặc biệt module này có 7 chân I/O giúp thiết lập ma trận 19 nút bấm (4*3+7=19) để ta play nhanh 19 file khác nhau ứng với từng nút.
