Microphone Board, Voice Audio Microphone Module Adjustable Gain, Module, Amplifiers Amplifier Module Module for Audio Component Amplifiers

Specification: Item Type: Microphone Board Power Supply: DC 2.6-10V Input: Equipped with a capacitive microphone (58D sensitivity) Output: 3.5 audio output and output ports audio sync pin 3P L and G (G: audio ground) Board size: Length: approx. 45mm/1.8in Width: approx. 25mm/1in Positioning Hole Diameter: Approx. 3.1 mm/0.1 in Power interface plug line: approx. 15 cm/5.9 inches Packing List: 1 microphone amplifier module 1 pin 1 pin header 1 interface cable Note: 1. The board is battery-powered as much as possible, which means two or more dry batteries or single 18650 lithium batteries and the like, which has a good effect. 2. The second is the source linear feed. If a switching power supply is required, add a filter circuit to maintain the circuit's power supply pattern. The smaller the wave, the greater the ripple and the greater the noise.
