In everyday life we are surrounded by sound in various forms. Therefore, there are more and more electronic devices in our environment that generate sounds, receive them or perform both functions simultaneously. Broadly understood acoustics consists of many important elements and devices, such as transducers: microphones, speakers or simple buzzers. These components can also be used as accessories to larger devices or their most important elements. We are aware of how important acoustics is in everyone's life and that it is an interesting topic for building projects and experimenting with electronics. That is why in our Botland shop we have prepared a wide range of parts, modules and kits, which can serve you to build your dream device or learn how to design. If you have any doubts or questions, please contact our technical department, who can give you advice or help you choose the right components. We will be more than happy to help you.

Starting to learn acoustics from scratch requires the supply of all necessary modules, parts and devices. Therefore, in our Botland shop we do our best to gather all the most popular products from trusted suppliers at great prices. In our offer you can find various types of microphones: from simple and very cheap electret microphones to modern MEMS microphones. You can also find modules with microphones. Depending on your needs you can also find a wide range of speakers. We have special simple and cheap devices if you just want to play simple sound signals. If you're looking for a device that can play high quality, high-powered music, you'll also find many hits here. The power of our speakers ranges from 0.1-200W. You can also find buzzers, both active with a built-in generator and passive. If you are trying to build an alarm system, you can choose powerful alarm sirens. We are sure that everyone can find what they are looking for.
An important function of acoustic devices is also sound playback and recording. We are doing our best to help you discover with us how easy it can be to incorporate these modules into your projects. In our offer you can find music players for such formats as MP3, WAV, OGG and MIDI. They are small, but very functional. In addition, you can also choose modules for sound recording and compact audio amplifiers. All modules are comparable to connect with Arduino, Raspberry Pi and many other minicomputers and evaluation modules. If you only want simple sound detection, you can find modules with microphones that catch loud sounds from the robot's environment. This is a simple operation without the need for cumbersome microphone signal analysis. Most modules in our offer are in the form of shields for Arduino and Raspberry Pi Hat overlays. This makes it easy to connect the tiles and program them. In our Botland shop you can also find simple modules with single buzzers and microphones with preamplifiers. Check our product list and see that we have what you need!
Our offer also includes a wide range of audio products for computers. First of all, various speakers are worth attention. You can find 2- and 3-channel speakers, which contain extremely functional computer speakers with a USB port. However, the speakers can also be used for other purposes. You can connect them with the Raspberry Pi as an audio set for a miniature media center. You can also find an extremely wide range of headphones in our offer. We've developed a small range of wired and wireless Bluetooth headphones. In addition, we also have large headphones with high sound quality and a built-in microphone - something ideal for avid gamers. In a separate section you can also find comfortable portable Bluetooth speakers, which are great for travelling and parties.
