1.
The module worked properly after a 24-hour test in ambient temperature at
25 °C, and the IOs in three domains (VDD3P3_RTC, VDD3P3_CPU, VDD_SDIO) output
high logic level to ground. Please note that pins occupied by flash and/or
PSRAM in the VDD_SDIO power domain were excluded from the test.
2.
Please see Appendix IO_MUX of ESP32 Datasheet for IO ’ s power domain.
