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

Based on the textual description of your project, here are a few areas that might need attention or clarification:
Duplicate Designators:
There are duplicate designators for RXD, GND, EN, 3V3, and TXD. Ensure each designator is unique unless intentionally meant to represent the same net.
Unconnected Pins:
It seems no electrical connections have been made yet in the project. You will need to connect pins to form a proper circuit. Start by identifying the purpose of each pin and connecting them accordingly based on your design requirements.
Power Supply:
Verify how you plan to supply power to the board. Ensure you have connections for 3V3, 5V, and GND where needed.
ESP32 Specific Connections:
For a typical ESP32 setup, you need to connect the EN pin to 3V3 through a pull-up resistor and ensure IO0 is grounded during boot mode.
Pin Functionality:
Make sure each pin (e.g., IO0, IO14, IO35, TXD, RXD, etc.) is assigned a function that's consistent with your application needs. Cross-reference with the ESP32 datasheet or module documentation.
RS-485 Transceiver:
If you are planning to use the 485_EN pin, ensure it's correctly connected as per your RS-485 transceiver application.
Please address these points and let me know if you would like help with making specific connections or have further questions!

In order to suggest a suitable MOSFET that operates at a Vgs (Gate-to-Source voltage) of 3.3V, you would need to consider a logic-level MOSFET. Typically, standard MOSFETs require a higher Vgs, often around 10V. Logic-level MOSFETs, however, are designed to be driven at lower voltages, making them compatible with 3.3V logic circuits.
Take the IRLZ44N as an example. It's a popular logic-level MOSFET that can work well at 3.3V on the gate. Here are some features of this MOSFET:
It is an N-Channel MOSFET.
It offers a Drain-Source voltage (Vds) up to 55V.
It allows a continuous drain current (Id) upto 49A.
Moreover, its Rds(on) is 0.022 Ohm at Vgs=5V.
Please notice that the key specification to look for when choosing a logic-level MOSFET for a 3.3V circuit is the threshold voltage (Vgs(th)), which indicates the minimum Vgs needed to switch on the MOSFET. For robust operation, you would typically want your operating Vgs to be significantly higher than the Vgs(th), which often is in the range of 1 - 2V for logic-level MOSFETs.
In addition, pay attention to the total power dissipation and ensure that it will not exceed the MOSFET's maximum rating in your application. These values can typically be found in the datasheet for the specific component.
However, as I don't have access to a database of components, I'd recommend verifying these features and comparing various models in order to select the best one for your application.
Once chosen, you can then integrate it into your project using Flux.ai. For example, you could connect the drain of the MOSFET to a load, the source to the ground, and the gate to the IO pin of your ESP32 (for instance, IO2). Please ensure to add an appropriate Gate resistor between the microcontroller IO and the MOSFET gate to limit the inrush current.
Remember to verify this configuration to ensure it aligns with your design goals and specific application requirements.
Sure, here is a basic pin configuration for designing an MCP23017 module:

`$SCL$ (I2C clock line)
`$SDA$ (I2C data line)
`$RESET$ (Reset input, a low level on this pin resets the device)
`$A0$ (Hardware address pin)
`$A1$ (Hardware address pin)

Just remember to define the I2C address of MCP23017 based on the combination of the status of the pins A0, A1, and A2. They are used for cascading MCP23017 on the I2C bus.
Please note the usage of each pin and their connections may vary based on your specific requirements and the rest of your circuit design. The above description assumes a standard application of the MCP23017. If you provide more specific details about your project, I can help you with a more customized pinout.
Sure, I'll guide you on how you can connect the MCP23017 module to the ESP32 WT32-ETH01 module using an I2C interface.
Assuming this MCP23017 is added to your circuit with the designator U2, here are steps to connect it:
I2C communication pins:
Connect U2:SCL(Pin 12, MCP23017's SCL) to WT32-ETH01:IO22(or any pin designated as SCL on your ESP32 module).
Connect U2:SDA(Pin 13, MCP23017's SDA) to WT32-ETH01:IO21(or any pin designated as SDA on your ESP32 module).
Power supply pins:
Connect U2:VDD(Pin 9) to WT32-ETH01:3V3 (if present, else to a suitable 3.3V power source).
Connect U2:VSS(Pin 10) to a common GND on your WT32-ETH01 module.
Reset pin:
Connect U2:RESET(Pin 14) to a suitable I/O pin on the WT32-ETH01 if you're planning to control the RESET function from software, or tie it to VDD if you want to keep the module out of reset mode.
Note that the above connections are assuming default GPIOs of the ESP32 for I2C. Depending upon your code and how you define the SDA and SCL pins you might need to modify IO22 and IO21 to match your settings.
Remember to write software that sets up and addresses the MCP23017 module properly over I2C communication. Also, make sure to provide pull-up resistors at the SDA and SCL lines because I2C bus specifications require them.
Please be aware that my assistance is based on the assumption that typical values for these parameters apply to your project. If this assumption is incorrect or if you have any specific requirements that haven't been mentioned, please feel free to correct me.
I'm sorry for any misunderstanding, but as a text-based AI, I am unable to directly manipulate your Flux project or directly add components in the Flux application.
However, I can guide you through the steps:
Open your Flux.ai project.
Click on the 'Component' or 'Part' toolbar, this might be symbolized by a plus sign or something similar, depending on the version of the tool you are using.
In the search bar that opens up, type 'MCP23017' and select it from the list of components that shows up. Click on 'Add part'.
Place the component on your schematic by clicking on your desired point.
Once the MCP23017 is on your board, you can start wiring it with the ESP32 WT32-ETH01 module, as I illustrated in the previous response.
If the MCP23017 module is not available in the Flux.ai component library, you may need to add it manually by creating a custom component or importing it from another library.
Remember to save your project periodically when making significant additions or changes to your design.
