FN-RM01 may be a high-quality MP3 audio recorder and player module, Flexible sound recording modes including MIC recording, Line-in recording and stereo 2-channel Aux-in recording, optional sound recording bit rates, multiple formats of audio files playback supported including MP3, WAV and WMA, and also as simple communication control modes are the most advantages of this module, which may meet sorts of needs from customers.
FN-RM01 supports standard UART asynchronous serial control(communication baud is 9600bps), working at 3.3V TTL level. Possible to be converted to RS232 level via MAX3232 chip.
FN-RM01 supports SD card and USB flash drive because the storage devices. When the two storage devices exist in the same time, choosing one among both to figure with the module is required. By default, SD card is the priority storage device. Whenever a shift is formed , it might be better to send the query command to verify if the shift is successful firstly. It’s possible for FN-RM01 to settle on an audio-recording input mode among 3 of them as above. By default, the module works with MIC audio-recording input mode.
Returned data: 00 represents command is executed successfully; 01 represents command execution failed;
It’s possible for FN-RM01 to set audio-recording quality/to choose audio-recording bit rate(code rate) as above.
By default, it is 128Kbps. The fixed sampling rate is 48KHz. Its features Involve:Supports microphone(mono), line-in(mono), and Aux-in(stereo) audio recording modes.
Supports AD keys control mode(play/pause, next, previous, record, and stop). Supports standard UART serial communication control mode. Supports playback of MP3, WAV, and WMA formats audio files, with great sound quality. Supports up to 48Khz rate and 128Kbps bit rate of high-quality MP3 sound recording .
