Hi guys.
In my project an Arduino board needs to talk to a TV using RX/TX port over 115200 baud rate and at the same time it needs to connect to wifi and send some data can Arduino Uno wifi do that?? or can you please suggest a model with these capabilities??
Maybe an esp-01 will be sufficient.
To make programming the esp-01 easier, programming adaptors are available.
Post more details and we can give more specific and accurate advice. Post details of the TV and it's serial connection, and what will be connected via wi-fi.
no esp-01 is not I need at least 8 digital pins and 5v output
Please try to give a complete list of all your requirements in your question. Otherwise you only waste the time of those trying to help you.
8 or more digital pins could be added to esp-01 with an i²c I/o expander.
Why is 5V output needed?

well. I am using 4 push buttons that switch the mode of my Arduino code. and an i2C LCD display and a 220v relay and these two requires 5V output
NodeMcu should be able to meet all those requirements. If not, one of the ESP32 boards.
NodeMCU does not provide 5V Output as I mentioned before
A maker friendly NodeMCU is a good choice if you need Wifi and 6 pins. If you need several HW Serial, consider board with an ESP32.
if you think you need 5V Output you can add a level shifter to that lines
Most of the typical 5V relay boards work fine with the 3.3 level of the ESP as input signal.
LCD's are available for 3V3 also.
mmmm how about Arduino Uno wifi?? I mean why should I convert the voltage when I can use built-in 5v output boards?? I don't have any problem with the board's size even mega is ok for me. But I wanna know that Arduino Uno can handle that or not?
The UNO doesnt have WiFi. I'd use an ESP32 board.
I think the OP means this:

Why do you want to limit yourself with a 16MHz board and 48KB Flash when you can get alternatives which are faster, have more memory and as side note are even cheaper?
Money doesn't matter. Nevertheless do some research and compare how many Arduino Uno Wifi questions get asked and answered here vs. ESP8266/ESP32 ... at least for me the community support will add an significant advantage for a platform decision.
