Raspberry Pi DigiAMP+ - High-Fidelity Audio Amplifier HAT

Bring superior sound performance to your Raspberry Pi projects with the Raspberry Pi DigiAMP+, a compact yet powerful audio HAT designed for direct connection to passive stereo speakers. Featuring the Texas Instruments TAS5756M digital amplifier, this board delivers up to 35W per channel of high-quality audio, making it the perfect foundation for Raspberry Pi-based hi-fi systems.

Powered by a 12–24V external DC source, the DigiAMP+ not only drives your speakers but also supplies power directly to your Raspberry Pi via the GPIO header — eliminating the need for a separate power input to the Pi. This board is fully compatible with all Raspberry Pi models featuring a 40-pin GPIO connector.

Formerly known as the IQaudio DigiAMP+, this HAT maintains a small footprint while offering professional-grade audio output, flexible installation options, and plug-and-play ease for your DIY audio or streaming setups.
