Frequently Asked Questions
Q: What microcontrollers is the LM386 sound detection sensor module compatible with?
A: The LM386 audio amplifier module is compatible with a wide range of microcontrollers and development boards that operate at 3.3V or 5V, including Arduino Uno, Arduino Nano, Arduino Mega, ESP8266, ESP32, and Raspberry Pi. Its broad supply voltage range of 3.3V–5.3V makes it highly versatile for most hobbyist and professional DIY electronics projects.
Q: Can this module be used for both sound detection and audio amplification?
A: Yes! The LM386 module serves a dual purpose. It can detect ambient sound levels (acting as a voice/sound sensor) to trigger actions in your circuit, and it can also amplify low-level audio signals to drive small speakers. This makes it a great all-in-one solution for audio-related microcontroller projects.
Q: What is included when I order the 2-piece set?
A: When you select the 2-piece option, you will receive two individual LM386 audio power amplifier and sound detection sensor boards. Each board is brand new and individually packaged in an SMD form factor, ready for use in your electronics project or as spares.
