TOOGOO (R) LM386 audio amplifier module 200 times 5-12V 10K variable resistor (Electronics)
Used the module to check whether the microphone capsule is working or not. But it serves its purpose. For me, however lacked the LED for power display. On D1 are just two solder points without the LED - not important for me. Pins 1 and 8 are connecte
