The SoundPAL is a tiny module that plays canned and custom sound sequences. It is completely self-contained, including a microcontroller for generating the sounds and a small speaker for producing them. The SoundPAL interfaces easily to a BASIC Stamp and can play sounds while the BASIC Stamp is busy with other chores.

Features

• Plugs into servo headers, and works with protoboards.
• Virtually goof-proof power sourcing makes it nearly impossible to connect wrong.
• Single-pin interface uses a simple serial protocol to define and initiate sound production.
• Canned tunes and sound effects can be played with simple commands.
• Custom tunes and effects are simple to program using musical notation instead of frequencies.
• Total audio range is 6½ octaves in four different tempos and four playing styles.
• Onboard EEPROM permits saving custom sound sequences for later playback.
• Autoplay feature permits playing a pre-designated EEPROM sequence with only a power supply.
• Compact size: stackable side-to-side with additional modules on 0.1" servo headers.

Key Specifications:
