product manual:
Small size design, full-chip technology production, the input and output coupling capacitors use imported non-polar brand capacitors, and the op amp uses the original low-voltage power supply TDA1308
Patch. It can work within 3-6V to meet the needs of low-voltage power supply occasions.
Board size: 33*25*8mm (length * width * height)
Working voltage: DC 3-6V
Note: The board does not have a regulated power supply. It is best to use a bent voltage power supply or battery power supply when installing, otherwise there may be interference.
If you feel that the default magnification is not appropriate, you can change the magnification by yourself, as follows:
Magnification adjustment:
R7 and R5 are the magnification setting resistors. You can change the magnification according to your own needs. The resistance can be selected from 5K-47K. The larger the resistance, the higher the magnification. If you use plug-in resistors, you can remove the original chip resistors. Solder the plug-in resistance to the pads reserved at both ends of the patch position.
