The JustBoom Amp HAT is a top - notch audio amplifier crafted especially for the Raspberry Pi. It comes with digital - to - analog conversion, eliminating the need for external sound cards or DACs. Simply stack this plug - and - play add - on board (HAT) onto your Raspberry Pi A+, B+, 2B, or the new 3B, and you're good to go right away! Designed for easy installation and use, no soldering is required, and all mounting hardware is provided. This makes it perfect for both beginners and experts. Connect it to passive speakers, and within minutes, you'll be enjoying high - quality, flawless audio playback. An optional IR receiver is included for remote control of your Raspberry Pi Amplifier. Featuring a Class - D power amplifier chip with a built - in 192kHz/32 - bit DAC, it has a peak power output of 2 x 55 watts. It outputs audio through two speaker cable connector blocks that can accept up to 14 AWG cable, providing clear audio to 4 or 8 ohm passive speakers. The I²S interface for audio input reduces CPU load on the Raspberry Pi compared to USB solutions. It can also back - power the Raspberry Pi over the 40 - pin GPIO header, so you only need one power supply for the whole system. Remember, you need the Global Power Supply or a suitable one to power this HAT. Key features include full high - quality 192kHz / 32 - bit audio, 2 x 55 watt peak output at 8 ohms (2 x 30 watt RMS), combined DAC and power amplifier, back - powering the Raspberry Pi at 2.5A, plug - and - play ease, hardware and software volume control, onboard hardware jumpers for settings, mute/enable with GPIO22, no soldering, optional IR receiver, accessible unused GPIO pins, full driver support in Raspbian/NOOBS, and compatibility with many media players.
Using the JustBoom Amp HAT is super easy. First, stack the Amp HAT onto your Raspberry Pi A+, B+, 2B, or 3B. There's no need to solder anything as all the mounting hardware is provided. Next, connect it to a set of passive speakers. Once you've done that, it should be ready to play high - quality audio right away. If you want to control it remotely, you can use the optional IR receiver included in the package. When it comes to power, you need to have the Global Power Supply or a power supply that can power the HAT. Make sure the power supply is properly connected to avoid any issues. For volume control, you can use both the hardware and software controls on your Raspberry Pi. If you want to adjust the mute and gain settings, you can use the onboard hardware jumpers. Just be careful when handling the jumpers. As for maintenance, keep the Amp HAT in a clean and dry place. Avoid exposing it to extreme temperatures or moisture. Check the connections regularly to make sure they're secure. If you encounter any problems, refer to the Getting Started guide, JustBoom Tutorials, Software Guides, or JustBoom Boards Pinout documents.
