Class D Toolstick

Silicon Labs offers Class D Toolstick audio board


The Class D Toolstick demonstration and evaluation kit from Silicon Labs is a cost-effective, USB-based evaluation kit that enables developers to add digital Class D audio capabilities to 32-bit embedded designs, based on Silicon Labs’ feature-rich SiM3U1xx Precision32™ microcontrollers (MCUs). The new Class D ToolStick kit demonstrates how easy and economical it is to upgrade basic “buzzer/beeper” alert sounds used in personal medical devices, fitness equipment, high-end toys, small appliances, and other consumer electronics products to more sophisticated voice prompts, music, sound clips, and even streaming audio.
