Плата разработки аудио Bluetooth I2S, цифровое/аналоговое аудио | АНС-ДБ003М
The ANS-DB003M is a USB-to-TTL serial audio development board that supports development and debugging of devices such as the ANS-BT301M. Users can read or write module configurations using AT commands via a serial debugger. It supports debugging audio source inputs as BT, К, USB, и tf-карта, and audio source output as analog output SPK. In Bluetooth input mode, it supports BLE data transmission. The ANS-BT301M supports I2S for master-slave output; testing requires an I2S program and jumper wires.

Development Board Introduction:
Development Board Kit:
2. Test Environment Installation
1) Install the serial port driver on the computer (CP210xVCPInstaller.exe, consult an engineer for driver information)
2) Mobile Tools
2.1. Datios Mini Program
2.2. NetEase Cloud APP, и т. д..
3. Test Environment Setup
3.1. Plug the ANS-DB003M development board into the computer’s USB port; the LED indicator should remain lit.
3.2. Open “Serial Port Debugging Assistant + TCP/UDP” (Microsoft…) on the computer. (Download from store)
Instructions:
(1) Select the CP210X serial port number for driver installation;
(2) Select the correct baud rate (consult an engineer);
(3) Open the serial port;
4. Audio Input: BT
(1) The ANS-BT301M standard program defaults to BT input;
(2) Phone settings – Bluetooth – select ANS-BT301M, click connect;
(3) Open “NetEase Cloud Music” to play. To receive lyrics, send the command: AT+LYRIC=1 via the serial port tool;
(4) Bluetooth Data Transmission: Bluetooth data transmission defaults to command mode. Taking the serial port debugging assistant and the Datios mini-program as an example of data communication, to send a data pass-through command: AT+TPMODE=1
5. Audio Source Input AUX
(1) Insert a 3.5mm audio cable
(2) Switch the command sending mode to AUX mode: AT+MODE=AUX
6. Audio Source Input USB
(1) Insert a USB flash drive; the songs on the USB flash drive will play automatically.
7. Audio Source Input TF Card
(1) Insert a TF card; the songs on the TF card will play automatically.
