Notes

  1. ESP32-P4 calibration schemes not supported yet in IDF and ADC Continuous also lacks IDF support.

  2. SPI Ethernet is supported by all ESP32 families and RMII only for ESP32 and ESP32-P4.

  3. ESP32-C3, C6, H2 only support USB CDC/JTAG

  4. ESP32-P4 only supports Wi-Fi through another SoC by using esp_hosted.
