WizFi320 User Manual 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, VOH>=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. 4.
