Overview
The main component of the module is a simple microphone, which is based on the LM386 amplifier and an electret microphone. This module’s output is analog and can be easily sampled and tested by an Arduino.
Features:
- Easy to use
- Provides analog output signal
- Easily integrates with Logic modules on the input side of Grove circuits
- Compatible with the Seed Grove System

The brand new Nano Screw Terminal Adapter turns up the speed on your prototyping efforts by giving you a fast, reliable way to hook up your boards. This awesome add-on is exactly what seasoned makers have been crying out for, and is now available from the Arduino Store. Let’s take a look at this mini mechanical marvel. A solderless solution With a finished project, you’re likely to make permanent connections to your Nano by soldering it. Even if you’re connecting it using a header strip, the wires, components, sensors and accessories will be soldered, crimped or attached in a permanent way to the controller side of your project. It makes perfect sense to do this, when you’re looking for a reliable connection. The trouble with permanent connections like this is that they’re… well, permanent! Soldering and de-soldering during the design and prototyping stage can become a real chore. And it’s not good for the components or the board itself, either. The Screw Terminal Adapter is what you need. It’s something we’ve been asked for a lot, giving people a way to make robust, fast, easy connections that can be changed just as easily. Easy access to all I/Os The Nano Screw Terminal Adapter features a double row of headers. The Nano drops into the two inner rows, giving you a second, outer set that lets you connecting using jumpers, wires or what have you. Then you have a third row of connectors on either side of the adapter with a screw terminal for each pin. The perfect way to connect wires or components in a reliable, but easily changeable way. It’s never been easier to develop and design a project that with these connection options. There’s even a 9x8 prototyping area with through plated holes for adding extra components, connections or accessories. Of course, this doesn’t have to only be for prototyping. The screw terminal is a long-established, trusted connection option, so there’s no reason it can’t become a
