Parameters:
Board size: 18mm*15mm
Working voltage: DC3V-5V
Output about 30mw, can directly drive ordinary 32 ohm headphones
R5: amplification adjustment resistor, resistance value can be used 4.7k-100k (chip resistor next to the reserved plug-in pads, if there is no chip resistor or welding technology is not good, you can use plug-in resistor.) The higher the resistance value, the higher the gain
R6: for the microphone sensitivity adjustment resistor, shipping default for high sensitivity (resistance value of 0 ohms), resistance can be selected from 0 ohms -10K between (chip resistor next to the reserved plug-in pads, if there is no chip resistor or welding technology is not good, you can use the plug-in resistor.) , the higher the resistance value, the lower the sensitivity
