Easy to Install: Light in weight and compact in size, the sound detection board is very convenient to install. Specification: Item Type: Microphone Pickup Module Material: PCB Power Supply: DC 2.612.5V Input: The board is equipped with a capacitive microphone (58D sensitivity). Output: The board has audio output ports L and G (G is the audio ground). Application: For Microphone Sound Detection. Package List: 1 x Microphone Pickup Module3 x Accessory Note: The board should use battery power as much as possible (two or more dry batteries or lithium batteries such as 18650), or use a linear power supply. If a switching power supply is used, please add a filter circuit to ensure that the circuit power supply ripple is small. The larger the ripple, the larger the noise.
