                  Working voltage: 5V
                  With fixed mounting holes
                  Board size: 95 X 62 mm
                  Display chip with audio spectrum display, built-in multiple decoding algorithms
                  No need for filtering circuits, driving points, spectrum indications and many other indicators.
                  FFT201211 working mode selection, users can set functions as needed
                  Supports LED display of 12 * 11 (12 rows and 11 columns);
                  Single (12 * 11), two-channel (left 6 * 11, right 6 * 11) dot matrix LED display
                  12 * 11 large dot matrix (132 points) display, multiple display mode selection
                  Mono mode of operation can display more spectrum information
                  Designed for audio equipment, it is used in all types of audio output equipment;
                  Professional audio decoding, showing the frequency and amplitude of the audio signal;
                  Three display modes (flash, slow flash 1 and slow flash 2) to provide a cool visual experience;
                  Three sensitivity modes (high, medium, low sensitivity) are selected to suit different power supply environments;
                  Display refresh rate 1-4 refresh speed adjustment
                  Automatic audio gain adjustment, always showing visual effects;
                  Circuit test mode to meet test needs during production
                  The design circuit is simple, the performance is stable and reliable, and the current limiting resistor is directly driven to drive the LED.
                  Memory function, can permanently maintain the parameters set by the user
                  (There is no 3.5MM power cable docking audio cable, please purchase separately, this connection does not include)
                  The board has a 3.5MM audio port, which can be connected to the mobile phone MP3 MP4 IPAD iPhone can be output to this with the 3.5MM audio output port, to achieve the audio spectrum function (follow the music dance)!!!

                  Display function settings:
                  Channel selection
                  Left and right channel display position
