The manual explains the Inno-Maker RPI-HIFI-AMP module for Raspberry Pi, its features, hardware and software installation, and configuration steps.
The RPI-HIFI-AMP is a Class‑D audio power amplifier module designed to plug directly into a Raspberry Pi, providing high‑quality stereo sound for small indoor spaces. It delivers up to 25 W per channel and works with 4 Ω or higher impedance speakers.
The guide covers the module’s key features, hardware connection to the Pi’s 40‑pin header, required 12‑20 V external power, compatible software platforms (OSMC, Max2Play, Volumio, etc.), and step‑by‑step instructions for preparing a TF card, flashing the image, and configuring the system. This manual is written in Chinese.
