WM8782S Stereo Audio ADC - I2S Output Module

Bring an analogue audio source into an I2S project. This WM8782S-based ADC board provides a capture stage with configurable master/slave operation.

✅ Convert audio input to digital data - The ADC changes supported analogue audio into an I2S signal.

✅ Choose the clock role - Master and slave modes let the board fit different supported digital-audio arrangements.

✅ Match the input connection - The 3.5mm/RCA description provides options to check against the source.

Plan the Capture Path Before the Decoder

An analogue-to-digital capture stage needs the source level, gain, clock and receiving interface to work together. Confirm the actual input connections and mode settings before connecting the board.

This is an ADC input module, not an analogue-output DAC or a complete USB sound card. The stated bit depth and sample rates depend on the selected configuration. Verify power, logic levels and supported source levels to avoid clipping.
