HiFi-Amped Raspberry Pi Audio HAT Features Dual PCM5100 DACs,GPIO-Controlled Shutdown and TPA3110 Amplifiers

The HiFi-Amped Raspberry Pi Audio HAT is an Audio HAT with dual PCM5100A 32-bit DACs and TPA3110 class-D amplifiers, GPIO control shutdown, and more.

It delivers high-quality audio output with power options ranging from 4x 10W into 8 ohms at 13V to 2x 30W into 4 ohms in bridged mode at 16V, making it suitable for small and large speakers. The module supports Raspberry Pi 2, 3, 4, 5, Zero, and other boards with a compatible 40-pin GPIO header. It offers speaker terminals, an I2S interface for audio data, and an external 8-26V DC power input with a pass-through option to power the Raspberry Pi. The HAT includes a GPIO-controlled amplifier shutdown to minimize idle noise and works seamlessly with Raspberry Pi OS and Volumio for audio streaming or media center setups.
