24x16 384 LED Dot Matrix TTF Audio Spectrum Flashing According to Input Sound DIY Electronic Kit

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 24*16 large dot matrix (384 points) display, multiple display mode selection memory function, Chinese English screen display Optional Introduction to function settings Turn off the clock display function Single dual channel display selection Audio signal left and right selection in mono Turn on the buoy display to turn off the spectrum Audio spectrum display is arranged in order of frequency from low to high Display refresh rate 1-4 Sensitivity setting for receiving audio Time display font size setting Calibration clock settings Strip: 24 spectral component display Column: 12 spectral component display Grid shape: 8 spectral component display Block: 6 spectral component display Light function switch full light function Important parameters to adjust the spectrum display effect Level 1 fixed gain: for strong signals, connected to the rear stage of the amplifier Level 2 fixed gain: for stronger signals 3-level fixed gain: for weaker signals 4-level fixed gain: suitable for weak signals, connected to the preamplifier Automatic gain adjustment mode 1 5: automatic gain mode 1 Automatic gain adjustment mode 2 Automatic gain adjustment mode 3 Automatic gain adjustment mode 4 Parts List: Numbering Name Package Quantity R4, R5 330K R-0805 2 R8, R11 470K R-0805 2 R1 10K R-0805 1 R2, R3, R6, R7, R9, R10, R12-R23 10 R-0805 18 C1, C3 22 C-0805 2 C2 106 C-0805 1 C4, C5, C6, C7, C10, C11 104 C-0805 6 C8, C9 220UF SMD capacitor C aluminum electrolytic chip capacitor 2 D1-D384 LED LED-0805 384 D385 IN5819 D-OK 1 Q1-Q24 8550 SOT-23 24 Y1 24 MHZ Y-SMD-3 1 U1 FFT2416-LQFP LQFP-48 1 J1, J2 3.5MM Four-legged patch audio seat 2 DC1 DC3.5MM-SMD-ok 1 K1 SW-PB-Tact switch CM-3x6-MM-T-ok 1 P1 0 PCB 1 Package included: 1 x Spectrum DIY Kit
