Note:
• Soldering Pad 39 to the Ground of the base board is not necessary for a satisfactory thermal performance. If users
do want to solder it, they need to ensure that the correct quantity of soldering paste is applied.
• When ESP32 is powered on and off repeatedly by switching the power rails, and there is a large capacitor on
the VDD33 rail, a discharge circuit can be added to the VDD33 rail. Please find details in Chapter Peripheral
Schematics, in ESP-WROOM-32 Datasheet.
