What Stands Out
Versatile Tone Generation
The SW8B Buzz I2C Audio Tone Generation Board excels in generating a wide range of audio tones, making it ideal for various applications in embedded systems and DIY electronics.
Easy Integration
Designed for seamless integration with Raspberry Pi and Arduino platforms, this board simplifies audio projects, allowing users to focus on creativity without complex setup.
Compact Design
Its compact PCB design saves space in project enclosures, offering an efficient solution for developers requiring reliable audio output without sacrificing design aesthetics.
Product Details
- Generate up to 4 audible tones of different frequencies at one time. Since inductive piezo buzzers are used for tone generation the volume is constant.
- Also adds 4 more I/O or A/D channels to your project through I2C. On board solder-jumpers allow selection of 16 different addresses, and optional 2200 ohm bus pull-up resistors
- Many support videos and extensive documentation available online, including a micropython example to play midi files with this board
- Use up to 16 boards on the same I2C Bus to increase the number of simultaneous audio outputs
- Open source hardware and software
- Separate power inputs for buzzers and logic. 3.3V or 5V operation. 5V operation is possible while communicating on a 3.3V I2C bus, allowing mixed voltage circuits or analog inputs.
