Descriptions: Tips:This is Assembled - The operation of the spectrum and the use of instructions see the following functions to operate the video,without instructions! - Functional operation Vedio: player.youku.com/player.php/sid/XMTcxNjcxODA5Mg==/v.swf - The 16-segment audio spectrum display PCB size of 176 * 50mm, LED size of 167 * 41mm. - PCB board thickness of 14mm flattening, LED module thickness of 8mm, the total thickness of 22mm. Important: 1. The module is green, the power supply is DC 5V / 600MA, the maximum brightness under the whole board current does not exceed 600MA, use the output current of more than 600MA of USB power can be. 2. Module printing BG for the green, the printing of this row of the pin is + pole, the corresponding board + . 3. Equipped with 33 green modules, one more spare. 4. Pay special attention to the color and polarity of the LED module when welding. Be sure to remember the first row of pins, the LED module corresponding to the position of the solder bar, and the last welding position of the LED module. Features: 1. Support 32Hz-20KHz precision sweep, and in the 10Hz-20KHz range to do a reasonable channel settings. 2. Display flip function, 16-level brightness adjustment. 3. The spectrum of the main landing speed, peak lamp holding time, the decline in speed can be adjusted separately. 4. Has a smooth display and bottomless display mode, excellent AGC processing. So that signal display richer. 5. The use of professional with blanking constant current driver chip, LED lights no bright dark flashing problem. Package include: - 1PC 16 level LED Audio Spectrum Diy kits
