The Serial Wombat SW8B Buzz board combines the frequency output feature of a Serial Wombat 8B chip with 4 transistor driven coil based buzzers to create a board capable of generating 4 simultaneous tones, one per buzzer. This board is a convenient way to add audio feedback to a project, or to generate simple melody output. An available example shows how to play MIDI files using a micropython board and this Serial Wombat board. The remaining 4 unused I/O pins (WP0 to WP3) can be used as general purpose I2C I/O expansion pins with identical functionality to Serial Wombat PCB0029.
