The new HAT board (KIT_40W_AMP_HAT_ZW) is compatible with Raspberry Pi Zero W and Raspberry Pi 3 and 4. It leverages Infineon's MERUS multilevel class D amplification enabled by the MERUS MA12070P amplifier, which allows for filter-free amplifier design that does not need to use a filter-coil at the output filter. This reduces significantly the BOM cost and enables PCB area reduction. The board furthermore scores high output power in small form factor up to 40 W instantaneous peak power at 4 Ohm. The solution offers best-in-class efficiency and playback time up to 20 hours with a ~6700 mAh power bank. There is no need for additional power supplies, only a single 5 V/2.5 A USB power supply is required for both the Raspberry Pi and the HAT.
For a quick and easy audio system set-up, the board is compatible with the main Linux distributions such as Raspbian, Volumio, moOde Audio or JustboomPlayer. Dual-channel bridge-tied load (BTL) or single-channel parallel bridge-tied load (PBTL) configurations for Multiroom, TWS, or subwoofer applications are also possible.
