Description

R5 is the gain adjustment resistor, the resistance value can be 4.7k-100k (the plug-in pad is reserved next to the chip resistor, if there is no chip resistor or the welding technology is not good, you can use the plug-in resistor.), the larger the resistance , The higher the gain.

Basic parameters:

Working voltage: DC 3v-6v

Board size: 16mm*15mm

Default gain: 40db (you can also adjust the gain as needed, just change the resistance of R5)
