Power net portal is a special schematic object used to define a power or ground net. Power ports allow you to conveniently indicate a power net at any location in the design. Power nets of the same designator automatically connect throughout your design #portal #power

The ESP32-WROOM-32D microcontroller (U7) appears to be set up correctly for basic functionality. The 3.3V power supply is connected to the 3.3V pin, and multiple ground pins are connected to GND (Net 0). Capacitor C8 is connected between the 3.3V and GND pins to provide decoupling for the power supply.
However, I do not see any connections to the ESP32's reset (EN) or boot (IO0) pins. To ensure the microcontroller starts up correctly, it's generally a good idea to connect the EN pin through a 10kΩ resistor to the 3.3V supply and the IO0 pin through a 10kΩ resistor to ground. This sets up the default state for normal operation. For programming or updating the firmware, you may need to add a mechanism for pulling IO0 high.
Additionally, some of the connected IO pins may require specific configurations depending on what they are being used for in your design. It's essential to carefully review the ESP32 datasheet and technical reference manual and ensure the pins are being used and configured accordingly.
Great Scott! The ESP32-WROOM module has several GPIO pins that you can use for your project. Here's a list of the available GPIO pins on the ESP32-WROOM:
GPIO0 to GPIO19
GPIO21 to GPIO23
GPIO25 to GPIO27
GPIO32 to GPIO39
Keep in mind that some pins have specific functionality or roles associated with them, such as GPIO0 or GPIO2, which are used for boot-mode configuration. Additionally, some pins may be used in your circuit for other purposes, so make sure to check the schematic before assigning new connections.
In the current schematic, I see U7 (the ESP32-WROOM module) has IO15 (GPIO15) connected to DRIVEPWM. You can use the available free GPIO pins above, but double-check for any conflicts in the existing connections.
