Datasheet Amp2


Datasheet Amp2


The HiFiBerry Amp2 is a DAC/amplifier combination for alle Raspberry Pi models featuring a 40-pin GPIO header.


  • Stereo DAC with sample rates up to 192kHz/24bit
  • Up to 2x30W output power output
  • Uses a single external power supply 12-24V (see below) to power the amplifier and the Raspberry Pi
  • No soldering, comes as a pre-fabricated kit, just plug it onto the Raspberry Pi.
  • Comes with all components required to mount it.

Hardware and speaker connectors

L/R outputs can’t be bridged!

Note that the actual board might look a bit different. Layout and components might change without further notice. We do not guarantee a specific PCB layout or specific components.

The Amp2 will power the Raspberry Pi. It is powerful enougfh for any Pi up to the Pi4B. Note that additional hardware drawing lots of power (e.g. hard disks, displays) might require an external power supply.
