St
resses 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.

1. Th
e 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.
