Description
An audio module with a DAC converter designed to work with the Raspberry Pi. Supports I2S/DSD/Coaxial input, Analog/Coaxial/Optical/I2S output, 384K/32Bit decoding function and unique DSD clock jitter eliminator. The decoder board supports decoding of I2S and DSD digital audio signals coming from the Raspberry Pi, and can also decode external signals (configuration via buttons).
The board uses two LDO stabilizers for separate power supply of analog and digital circuits. High-capacity capacitors and tantalum capacitors are used for filtering and decoupling to ensure a stable and clean power supply.
The module is based on digital circuits, including PCM9211 (digital audio transceiver), PCM5122 (digital-to-analog converter), DS90LV047A (fast differential driver) and a crystal oscillator. The built-in OLED display can display the track's current sampling rate, the current decoder board input signal format and the I2S interface output format.
The module is perfect for building a high-quality audio system.
