Justboom Audio Amplifier HAT for Raspberry Pi
JustBoom Amp HAT is simple to install and use. With no soldering required and all the mounting hardware already provided this product is suitable for beginners as well as professionals. Get a high-quality audio playback within minutes by connecting this Raspberry Pi amplifier HAT to a set of passive speakers.
An optional IR receiver is also included to allow remote control operation of the Raspberry Pi Amplifier. Includes a Class-D power amplifier chip with built-in 192 kHz/32 bit DAC, for a maximum power output of 2 x 55 Watts. The JustBoom Amplifier HAT delivers audio over two speaker cable connector blocks that accept anything up to 14 AWG cable and will provide crystal clear audio to either 4 or 8 Ohm passive speakers. The Amp HAT uses the I2S interface for its audio input which reduces CPU load on the Raspberry Pi compared to USB solutions. It is also designed to back-power the Raspberry Pi over the 40 pin GPIO header, meaning you only require a single power supply for the entire system.
Additionally, all of the unused Raspberry Pi GPIO pins are still accessible on the Amp HAT for easy customisation of your project – add additional sensors, buttons, LEDs, rotary encoders etc.
- Hardware and software volume control from your Raspberry Pi
- Onboard, hardware jumpers for configuring mute and gain settings (jumpers could optionally be changed with switches)
- Mute/enable with GPIO22 (this can be overridden by using jumper J4)
- Compatible with Raspberry Pi A+, B+, 2B and the new 3B
