BassOwl-HAT

#Shared Projects

BassOwl-HAT is an expansion board for Raspberry Pi and ASUS ThinkerBoard, designed for Hi-Fi music playback.

It is powered by the TAS5825M from Texas Instruments, a stereo Class-D Smart Audio amplifier able to deliver up to 30W RMS per channel. BassOwl-HAT does not require any external device or amplifier to play music, two loudspeakers can be connected directly to the screw-terminal connectors.

BassOwl-HAT requires an external power supply with volgage between 12V and 24V to function properly. It is not necessary to connect additional power sources, because a dedicated 5V/3A DCDC converter will back-power the Raspberry Pi.
