Notes:
1. Please see Appendix IO_MUX of ESP32 Datasheet for
IO’s power domain. VDD is the I/O
voltage for a
particular power domain of pins.
2. For VDD3P3_CPU and VDD3P3_RTC power domain, per-pin current sourced in the same
domain is gradually reduced from around 40 mA to around 29 mA, V
OH >=2.64 V, as the number
of current-source pins increases.3. Pins occupied by flash and/or PSRAM in the VDD_SDIO
power domain were excluded from the test.

1.
Device should operate in the frequency range allocated by regional
regulatory authorities. Target operating frequency range is configurable by
software.
2.
For the modules that use IPEX antennas, the output impedance is 50 . Ω For
other modules without IPEX antennas, users do not need to concern about the
output impedance.
3.
Target TX power is configurable based on device or certification requirements.
