# Pi-DigiAMP+
|
||||
|
||||
The Pi-DigiAMP+ is an add-on board that includes a Digital to Analog Converter (DAC) and powerful 35w stereo amplifier. If you want to turn your Raspberry Pi into a working Hi Fi stereo, just add speakers and you're off.
|
||||
|
||||
The Pi-DigiAMP+ exposes some of the Pi's pins via a header.
|
||||
|
||||
Pin | Name | Name | Pin
|
||||
--- | --- | --- | ---
|
||||
1 | GPIO23 (Rotary encoder) | GPIO22 (Mute) | 2
|
||||
3 | GPIO24 (Rotary encoder) | GPIO25 (IR) | 4
|
||||
5 | 5v | 3v3 | 6
|
||||
7 | I2C SCL1 | Ground (0v) | 8
|
||||
9 | I2C SDA1 | Ground (0v) | 10
|
||||
|
||||
|
||||
These can be used for whatever you like but some are used by some additional software the IQAudIO provide to easily support a rotary encoder for physically controlling volume, a hardware mute switch and IR control.
|
||||
|
||||
The official documentation can be found on the [IQAudIO website](http://www.iqaudio.com/downloads/IQaudIO.pdf).

# Pi-DigiAMP+
|
||||
|
||||
The Pi-DigiAMP+ is an add-on board that includes a Digital to Analog Converter (DAC) and powerful 35w stereo amplifier. If you want to turn your Raspberry Pi into a working Hi Fi stereo, just add speakers and you're off.
|
||||
|
||||
You can use GPIO25 to connect an IR sensor and GPIO23/24 for a rotary encoder. Both of these parts are optional, but are broken out on the Pi-DAC+ for convenient access.
|
||||
Note: pins reserved for the rotary encoder and IR sensor can be used for other purposes if those add-ons have not been fitted and enabled by software.
