- /*
- * board_config.h — hardware pin map for the ESP32-P4 Dante/AES67 endpoint.
- *
- * Target board: Waveshare ESP32-P4-ETH (Ethernet via IP101 GRI PHY on RMII,
- * onboard ES8311 codec + NS4150B amplifier + mic + 8ohm speaker connector,
- * 32MB PSRAM, 32MB flash). Pins verified against the board schematic
- * (docs/esp32-p4_schematic_en.pdf). Values mirror the pin table in README.md
- * — if the board ever changes, update BOTH this file and the README table
- * together (see CLAUDE.md).
- *
- * Note on I2S data direction: DOUT (GPIO9) drives the codec's DAC serial
- * input (ES8311 DSDIN); DIN (GPIO11) reads the codec's ADC serial output
- * (ES8311 ASDOUT).
