5.1 Absolute Maximum Ratings
Stresses beyond the absolute maximum ratings listed in the table below may cause permanent damage to the
device. These are stress ratings only, and do not refer to the functional operation of the device that should
follow the recommended operating conditions.
Table 5: Absolute Maximum Ratings
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.
2. Please see Appendix IO_MUX of ESP32 Datasheet for IO’s power domain.
