IQaudio sound cards are all designed to work with the current Raspberry Pi and those that have a 40way male GPIO pin header. This includes Raspberry Pi 4B, 3B+, 3A+, 3, Zero etc. Some of our products are full-size HAT boards for the full-size Raspberry Pi, and others are more suited to the Raspberry PI Zero form factor.

DigiAMP+ is a HAT compliant add-on accessory for the Raspberry Pi.

DigiAMP+ uses the Texas Instruments TAS5756M PowerDAC to deliver direct connection to PASSIVE stereo speakers at up to 2x35wpc with variable output. Ideal for a Pi based HiFi.

DigiAMP+ can be connected to the Raspberry Pi A+/B+/RPi2/RPi3 or RPi4's 40way pin header without any additional soldering.

DigiAMP+ must be powered from an external supply and requires a 12 to 24DC power source to 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.

Note: 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!
• P8: TAS5756m Internal GPIO1/2/3
