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.
