Development board

Helike UA-E3010

Tap into the latest speaker technology for your audio project: Helike is a universal application platform for evaluating, rapid prototyping and designing audio solutions using USound MEMS speaker technology. The board can be used as a stand-alone component but is also compatible with Raspberry Pi. It features an open-source software as well as PC-based configuration software for acoustic tuning.


Compatible with Raspberry Pi

The board functions in stand-alone mode, as an extension to Raspberry Pi platform, or even as a USB soundcard connected to a mobile device or a PC via USB-C.

Integrations and applications

MEMS speaker amplifiers (MEMS AMP), electrodynamic speaker amplifiers (Dynamic AMP) as well as a differential amplifier (Differential AMP) are mounted on the PCB to work with a variety of applications. An output connector section is present to interface to these loads and applications.

Rapid Prototyping

The board can be used for designing new customer solutions, rapid prototyping, and evaluating several USound audio solutions. Additionally, equalization presets are available for the compatible USound products.
