Product Description

Description:

Working voltage: 5V
Current 200MA
With fixed mounting holes
Board size: 136 X 210 mm
Display chip with audio spectrum display, built-in multiple decoding algorithms
No need for filter circuits, driving points, spectrum indications and many other indicators.
The board has a 3.5MM audio input port that can be connected to the mobile phone. MP3 MP4 IPAD iPhone can be output to this as long as it has a 3.5MM audio output port to achieve audio spectrum function (follow music dance).

Function introduction:
 
Audio spectrum display driver chip, built-in multiple DSP decoding algorithms (no program, can be used after soldering)
Clock display (actually no effect, power off time is gone)
Buoy display can be set when the spectrum is displayed
A variety of work mode options, users can set the function as needed
Test mode to meet test needs during production
Single (24*16), two-channel (left 12*16, right 12*16) dot matrix LED display
Mono mode of operation can display more spectrum information
