[Munich, Germany, May 26, 2020]Infineon Technologies AG (FSE: IFX/OTCQX: IFNNY) has developed the world’s first fully self-contained Raspberry Pi audio amplifier hardware expansion board (HAT) . Not only is it compact, but it delivers high-fidelity audio at speaker power levels. Infineon’s proprietary multi-stage technology ensures that Raspberry Pi users and makers can enjoy minimal product size and power consumption, while maintaining first-class power efficiency and HD audio quality. Its target application area is active speakers that support wireless music streaming.

This expansion board (KIT_40W_AMP_HAT_ZW) is compatible with Raspberry Pi Zero W, Raspberry Pi 3 and Raspberry Pi 4. It utilizes the built-in MERUS MA12070P amplifier to realize the MERUS™ multi-stage class-D amplification function, and supports the design of filter-free amplifiers, eliminating the need for output filters to carry filter coils. This greatly reduces the BOM cost and reduces the PCB footprint. In addition, this expansion board has a small form factor, but has a high output power, which can provide up to 40W of instantaneous peak power at 4 ohms. This solution has excellent efficiency and can play up to 20 hours when using a power bank of about 6700 mAh. No additional external power supply is required, just a 5 V/2.5 A USB power supply can power the Raspberry Pi and the expansion board at the same time.

For quick and easy audio system setup, the expansion board is compatible with major Linux distributions such as Raspbian, Volumio, moOde Audio or JustboomPlayer, etc. It can be configured as a Binaural Bridged Load (BTL) or a Mono Parallel Bridge Type Loaded (PBTL) mode and can also be used in multi-chamber, TWS or subwoofer applications.

Availability

The Raspberry Pi Audio Amplifier Expansion Board is available now.
