nRF24L01 2.4GHz Wireless Audio Transceiver Module

The nRF24L01 is a 2.4G Wireless Digital Audio Module Wireless Speaker Transmitter and Receiver DC5V 44.1K Sampling rate, 24bit AD sampling to achieve nondestructive high-fidelity digital audio transmission 16-channel selectable maximum distance 100 meters on open ground.

It’s working current 50mA working channel 16CH input impendence 600ohm output amplitude of the audio signal 0.3-1v frequency 20hz-20khz.

Feature:

1. Input signal: analog sound
2. Output signal: analog audio
3. Working voltage: 3.5— 5V
4. GFSK digital modulation / demodulation method
5. 20Hz ~ 20KHz frequency response
6. 90dB audio dynamic range
7. 85dBm receive sensitivity, 45dB adjacent channel rejection, 30dB image rejection
8. 20Hz ~ 20KHz frequency response
9. 44.1K digital audio sampling rate, 16bit sample quantization level
10. Long transmission distance: stereo audio data can be transmitted over an open area of ​​more than 100 meters (static point-to-point)
11. Supports multiple transmission modes for point-to-point and point-to-multipoint (both simultaneous and multiple)
12. Key pair code can support multiple groups of non-interfering parallel work at the same time.
13. Multiple candidate frequency bands, easy to avoid interference frequency: This product works in 2.4GHz ISM (ie industrial, scientific, medical) frequency band, with 16 selectable frequency points to meet multi-frequency and frequency hopping needs; to avoid In the 2.4GHz public frequency band, the influence of the interference on the sound quality, the product provides the frequency selection function. If the product has strong noise during the working process, that is, when the interference occurs at the current frequency, the output sound quality is affected. New working frequency points can be selected to keep the product in good working condition.

Note:

1. Schematic attached in the tital pictures

2. Please connect the power on the item. input analog signal to the transmitter, then you will receive the signal in receiver

3. If the leds on both boards flick twice, the two boards get a pair

4. If there is other signal influence the board, please press the button on the transmitter. you will see the LED get flick, and the led on the receiver flick as well, they will jump to another channel. we have 16 channel.
