operate. DigiAMP s barrel connector is 5.5mmx2.5mm. DigiAMP has been designed to provide power to the Raspberry Pi and DigiAMP combination in parallel, delivering 5.1v 2.5Amp to the Pi.
DO NOT APPLY POWER TO THE RASPBERRY PI’s OWN POWER INPUT WHEN USING DIGIAMP .
The amplifier is by default muted at power on (mute LED lit). The mute state LED is under software
control (Raspberry Pi GPIO22).
P5 Alternative power input for hard wired installations. POLARITY MUST BE OBSERVED!

The DAC is a HAT compliant add on accessory for the Raspberry Pi A /B /RPi2 /RPi3 or PRi4. The DAC uses the Texas Instruments PCM5122 DAC to deliver analogue audio to the DAC ’s Phono connectors. The PI DAC also supports a dedicated headphone amplifier.
The PDAC can be connected to the Raspberry Pi’s 40way pin header without any additional soldering. The DAC is powered by the Raspberry Pi.
P1 Analogue out (0.. carries GPIO27, MUTE signal (headphone detect), Left and Right Audio and Left and Right Ground.
P6 Headphone socket signals (1: LEFT, 2: GROUND, 3: RIGHT, 4: GROUND, 5: DETECT)

The DAC PRO is a HAT compliant add on accessory for the Raspberry Pi.
The DAC PRO users the Texas Instruments PCM5242 to deliver outstanding Signal to Noise Ration and supports Balanced Differential out in parallel to Phono RCA line le vel output. It also includes a dedicated headphone amplifier.
The DAC PRO can be connected to the Raspberry Pi A /B /RPi2/RPi3 or PRi4’s 40way pin header without any additional soldering. The DAC PRO is powered by the Raspberry Pi.
Component selection an d track layout have been in the forefront of our design to ensure noise immunity and best possible audio playback with the DAC PRO.
The DAC PRO exposes two 3 pin headers P7/P9) used by the optional XLR board to provide
Differential Balanced output exposed by XLR sockets above the Raspberry Pi’s USB/Ethernet ports.
