AD828 piezoelectric ceramics front -stage amplifier board piezoelectric ceramics pickup module

Using AD828 or TDA1308 chip design.The use of piezoelectric ceramic pieces to pick up the sound, voltage ceramics have the characteristics of vibration vibration vibration that is transmitted to solids, not sensitive to the sound wave vibration of the gas, which can effectively reduce the environmental noise and avoid the screams produced by self -esteem.Can be used for guitar. Erhu and other musical instruments.

Board size: 25mm*16mm

Note: The board does not have stabilization of power supply, and the battery or voltage power supply should be used.Otherwise there may be interference.The board has been tested at the time of delivery. All the after -sale solder iron welded was not returned. If you disagree, please detour.

The resistance R5 on the board is adjusted by magnifying multiple. If the magnifying multiple is not suitable, you can adjust the resistance value of the R5 from 5K-150K. The larger the resistance value, the higher the magnification.Drop the original patch resistance, put the plug -in resistance welding on the pads reserved on both ends of the patch position)
