Vastarry Vacuum Fluorescent Display Music Spectrum Features
-
VFD music spectrum screen is a classical vacuum display device, with the pickup and STM32F103 processor, to display a unique music spectrum, 10 display modes; one key to learn environmental noise and calculate the display threshold; 2 sleep modes, built-in clock, can It is the clock, or it can be the audio spectrum, depending on the situation.
-
Horizontal distribution of 25 frequency bands, vertical display of frequency band voltage gradients, dual-mode input, silicon microphone (MEMS) and audio input, with STM32F103 processor, to analyze and display the sound spectrum.
-
Configurable functions: MEMS gain setting, noise learning setting, display speed setting, sleep pattern setting, clock setting.
-
Product size Length, height and width: 176x50x28mm, power supply: Type-c 5V-2A (can not use fast charging); 12V-1A (power supply should not have too much noise, clean power supply is the best),
-
Necessary matters needing attention: the light column on the far right keeps beating one bar in a quiet environment, which is a normal situation. The situation will only last for 10 seconds. After jumping to the clock, it will return to normal to avoid noise interference. The music spectrum needs to reach 3 bars when it starts. Brightness, (beaming bar below the clock), please know before buying.
About Vastarry Vacuum Fluorescent Display Music Spectrum
VFD music spectrum Electrical Characteristics: Input Voltage: 5V Type-C/12VDC Sleep current: 0.03A (5V) Working current: 0.3-08A (5V) Input channel: Audio input X1 Frequency Response: 600Hz-20KHz Input Impedance: 50kOhm Dimensions LWH: 176x50x28mm Screen material: glass Shell material: acrylic PMMA MCU: STM32F103 Display resolution: 25 segments and 15 levels Option Description: MODE??Display mode selection 0-10 GAIN - gain setting Range: 0-19 The gain is gradually increased, the default value: 0; LEARN??Noise learning setting, press up/down to enter noise learning mode, the bottom display A horizontal line, any sound produced during this process will be sampled as noise, saved, and will be filtered out as much as possible when actually displayed. SPEED??speed setting, 0-4 from slow to fast, the default value is 2; SLEEP??Sleep setting, 0: no sleep; 1: display the clock when quiet; 2: close when quiet; Sensitivity - 1. Adjustment of the back input attenuation potentiometer (for audio cable) 2. The GAIN option adjusts the internal gain (applicable to the pickup mode) ----------------- Precautions: 1. Please connect the power supply according to the specified parameters, so as not to damage the motherboard, please use the power supply certified by the relevant agencies; 2. There is high voltage in the machine, and it is forbidden to touch the exposed part during use; 3. Do not immerse in water, or use in conditions with humidity higher than 90%, only indoor or car use; 4. Do not use any solvent or liquid other than anhydrous alcohol to wipe the screen; 5. Glass vacuum device, no vibration;
