KW-Commerce I2S ADC Audio Capture Card Module 2 in 1 accessory

SKU CH-CXD3-ZZ6SS

Converts analogue audio to I2S digital output at up to 24-bit 192 kHz with 3.5 mm input and 6 dB gain

  • Converts analogue audio to I2S digital signal
  • Master mode offers 24-bit at 192 kHz and 96 kHz
  • Slave mode supports 24-bit 192 kHz, 96 kHz, 48 kHz and 16-bit 48 kHz
  • Auto output defaults to 24-bit 192 kHz or 96 kHz I2S on power-up
  • 5 mm input with 6 dB gain for stronger capture

I2S ADC audio capture card module

The KW-Commerce I2S ADC audio capture card module converts analogue signals into I2S digital audio streams. It operates in master or slave modes for development and prototyping work. A 3.5 mm input with 6 dB amplification is provided as standard.

Makers needing lossless I2S capture

Engineers building custom audio interfaces or experimenting with digital signal processing will find the flexible sample-rate options useful. Users who require integrated analogue-to-digital conversion with USB or network output should look elsewhere.

24-bit depth at 192 kHz headroom

The board handles 24-bit audio at 192 kHz and 96 kHz in master mode, plus 24-bit at 48 kHz and 16-bit at 48 kHz in slave mode. Projects demanding higher bit depths or sample rates beyond these limits will exceed its capability.

Highlights

  • Converts analogue audio to I2S digital signal

  • Slave mode supports 24-bit 192 kHz, 96 kHz, 48 kHz and 16-bit 48 kHz
  • Auto output defaults to 24-bit 192 kHz or 96 kHz I2S on power-up
  • 5 mm input with 6 dB gain for stronger capture

Questions about this item

What external hardware is required to receive the I2S output from this capture card module?

You need a device with an I2S input such as a DSP board, microcontroller or audio processor that accepts 24-bit 192 kHz or 96 kHz streams.

Will the module work with a legacy DAC that only accepts 16-bit 48 kHz I2S?

Yes, set the module to slave mode and select 16-bit 48 kHz; the card will then output a compatible I2S stream for the older DAC.

How can I verify the board is converting the analogue input to I2S after power-up?

Apply a signal to the 3.5 mm input, then monitor the I2S data line with a logic analyser or scope to see a continuous 24-bit 192 kHz or 96 kHz bitstream.
