Placa de Expansão I2s Hifi Dac Digital Áudio Placa de Som Decodificar Codificador para Raspberry pi 2b 3b 3b Mais 4b Nvarcher-es9018k2m

2. Using high-precision active crystal oscillator, solid capacitors are used for main filtering, and ruby electrolytic capacitors are used for positive and negative voltages.

3. High-precision chip resistors are selected for the resistors to ensure a good signal-to-noise ratio of the whole machine.

4. The I2S input adopts XH2.54 6P socket, and the coaxial input is welded.

5. The RCA lotus seat is the standard and high-end equipment.

Basic parameters:

Input power: DC 5V 0.5A

Board size: 53*48MM

Mounting hole size: 43*38MM
Distance between two RCA output sockets: 20MM

Input support:

I2S/DSD: 32bit 384k/DSD64, DSD128, DSD256

Signal input description:

Coaxial version: The I2S seat is reserved, but the I2S input channel is closed, the input I2S signal input is invalid, and only the coaxial signal can be input.

I2S version: No coaxial signal input function, coaxial signal input is invalid, only I2S signal can be input.

I2S pin Description:

Lead wire description: I2S and coaxial input can only choose one of the two, and cannot be input at the same time, otherwise the sound conflicts.

Main selling points:

1: Used in conjunction with the interface, there is no defect in PCM DSD switching.
2: DC power supply 5V0.5A, easy to use.
3: ES9018K2M parameters are relatively complete, 127dB DNR -120dB THD+N is not comparable to the old chip.
4: The board size is 53X48MM, and the small size is easy to install.

The MCLK of ES9018K2M is an independent clock and can use 50Mhz-100Mhz, so only input DATA BCK LRCK is enough and very convenient. Polishing CD DVD old decoding effect is very good. It is delicate and round, and extends very well.

Frequently Asked Questions:

1. Why does I2S have 6 wires Isn’t it normal that there are 4 wires

Answer: ES9018K2M integrates MCLK, but it is designed to facilitate upgrading to a better MCLK master clock. You can upgrade the OCXO or femtosecond clock independently. The crystal oscillator on the board must be removed when upgrading the clock.

2. Can you support the supporting use of those development boards

Answer: Support Raspberry Pi 2B+ 3B 3B+ 4B, ASUS tinker board S, Songguo ROCK 64 development boards
