Board features

IQaudio DAC Pro connects to the 40-pin GPIO header of Raspberry Pi 1 Model B+, Raspberry Pi 2, Raspberry Pi 3, or Raspberry Pi 4 with no need for soldering or external power.

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 Raspberry Pi’s USB/Ethernet ports.

• P1: Analogue out (0..2VRMS), carries GPIO27, MUTE signal (headphone detect), Left and Right Audio and Left and Right Ground.
• P6: Headphone socket signals (pin1: LEFT, 2:GROUND, 3: RIGHT, 4:GROUND, 5:DETECT)
• P7/9: Differential (0..4VRMS) output (P7:LEFT, P9: RIGHT)
• P10: Alternative 5v input, powering the Raspberry Pi in parallel
