X400 V3.0
Contents
Overview
This is a redesigned X400 audio expansion board. We have adopted a lot of customer feedback on the previous version. We have made many improvements based on the previous version. I believe you will like it.
Features
- Full-HD audio – up to 24-bit/192kHz playback
- Audiophile TI Burr Brown 32-bit/384kHz DAC (TI PCM5122)
- Class leading audio; 112db SNR, and THD of 0.0019%
- Built in High quality Class-D stereo audio amplifier (TI TPA3118D2)
- Up to 2×30W Into a 8-Ω BTL Load at 24Vdc
- Capable of driving 4 Ohm speakers (also works with higher impedance speakers)
- Built in high quality audio headphone amplifier (TI TPA6133A)
- Uses the Texas Instruments ultra-low-noise voltage regulator (output noise< 10μVRMS)
- Uses the Texas Instruments high efficiency step-Down DC converter (up to 95%)
- 6V~26Vdc converted to 5.1V, 3A to power the Raspberry Pi
- Uses the genuine ALPS RK163 series potentiometer for smooth volume adjustment
- Built in high quality IR sensor (Vishay -the world's leading supplier of infrared receivers)
- Onboard RCA connectors
- Onboard 3.5mm stereo headphone jack
- Onboard speaker & power screw terminals
- Onboard 4pin PH2.0 connector allowing to connect a external lighted power switch to control power
- Onboard gold-plated high-current DC power jack (5.5x2.5mm)
- Uses the digital I2S audio signals to reduce CPU load over USB audio solutions
- Connects directly to the Raspberry Pi - No wiring required
- Powers the Raspberry Pi - no additional power supply
- Reserved Raspberry Pi GPIO pin header (2x13Pins)
- Pop-noise can be improved by enabling GPIO control
- AMP can be enabled / disabled with jumper link
WARNING:
DO NOT APPLY POWER TO YOUR RASPBERRY PI VIA THE PI's MICRO USB SOCKET.
