Description
N1 Audio DAC Board Hifi Decoder Board Supporting Coaxial Optical I2S Analog For Raspberry Pi 3B+4B
Features:
- Audiophile DAC board for Raspberry Pi
- Support I2S, coaxial and DSD input. The N1 audio decoder board supports I2S and DSD digital audio signal decoding on the motherboard for Raspberry Pi. You can also set and decode external coaxial signals through the three buttons on the board
- 384K/32Bit decoding function
- Unique DSD clock de-jitter
- Rich audio output interface. Support up to 7 audio output interfaces, easily adapt to high-end decoders. Supports 7 audio output modes, including analog, coaxial, optical, I2S, etc., and the audio output signal of each interface can be individually turned on or off through the button settings on the board
- OLED display makes it easier to operate
- Original chip + professional technical design. All imported original chips are used on the board, and two sets of LDOs are designed to supply power to the analog and digital circuits separately. And use large-capacity solid capacitors and tantalum capacitors for filtering and decoupling to ensure a stable and clean power supply and improve the output signal-to-noise ratio of the whole machine
- PCM9211 for TI. Professional digital audio transceiver chip supports up to 216K sampling rate, with ultra-low jitter function and performance of coaxial transceiver clock <50 RMS. It is better than AK4118
- PCM5122 DAC chip for TI. With up to 384K/32Bit decoding capability and 112dB high SNR and high dynamic range, the details are richer and the restoration is more realistic
- LVDS output. I2S and DSD output uses DS90LV047A high-speed differential driver chip for the National Semiconductor, supports a transmission rate of 200MHz, and ensures that the I2S/DSD signal is distortion-free
- American industrial grade programmable digital silicon crystal oscillator. It has ultra-low jitter and extremely low phase noise, and is recognized by the industry as the most reliable clock device
- I2S/DSD interface definition. I2S/DSD uses the HDMI interface to use differential signal output, and can be input to the DAC decoder with I2S input using a normal HDMI cable to obtain a better playback effect
- High-quality RCA gold-plated socket, HDMI connector for Foxconn
Output Interface Specifications:
- Analog audio: RCA/headphone 32K-384K/32Bit

- Optical fiber: PCM32K-192K/24Bit; DOP DOP64
- I2S: PCM32K-384K/32Bit; DOP DOP64/DOP128; DSD DSD64/DSD128
Product Specifications:
- Rated voltage: +5V (It can be powered by a motherboard for Raspberry Pi, or from the DC socket on the DAC board)
- Rated current: 300mA
- Motherboard size: 56 x 65mm/2.2 x 2.6"
- PCB material: 4-layer green military fiberglass board
- Production process: lead-free
- Support model: for Raspberry Pi 2B/3B/3B+/4B
- Support players: for Volumio, Moode, piCorePlayer and RuneAudio
Package Included:
- 1 x Set of DAC Board
Note:
- The motherboard for Raspberry Pi is not included in the package.
Attention:
1. The coaxial interface can be set to output or input by pressing the button, and it can only be set to one of them.
2. The I2S and DSD signals are input from the pins of a motherboard for Raspberry Pi, the I2S or DSD signals output by the HDMI interface are synchronized with the I2S/DSD output by the Pi, and the PCM9211 chip will de-jitter the DSD clock.
