Accidentally coneccted TX pin from Nodemcu to Rx Arduino Uno pin while flashing Arduino Uno and now Nodemcu is not recognized anymore

Hello, I've made a big mistake, i was following this tutorial Send Data From Arduino to NodeMCU and NodeMCU to Arduino Via Serial Communication - YouTube about how to connect my nodemcu to arduino uno because is an university project, but i left nodemcu tx pin connected to rx arduino uno pin while flashing arduino uno and now nodemcu is not read by arduino IDE anymore, can someone help me please? in new on this and idk how to make i readable again.

This really shouldn’t have caused a problem. :thinking:

Now if you said the other way around, all bits are off. :woozy_face:


Oh, while flashing the UNO, yes the nodemcu may now be jewelry.
However the UNO RX pin has a series 1k resistor to the USB chip which might have prevented physical damage.

Can a different nodemcu still be detected ?

Update!
The nodemcu connects to wifi and works well with my mqtt server, i sent messages and he answered, i flashed him with PL2303 and it worked, he got flashed well. The problem is that when i connect the esp-wroom-32 via usb wire the arduino IDE is not detected yet. I think the rx and tx pins are burned and now i cant send info to arduino again. I'm lost, my project must be presented tomorrow and i have not any nodemcu for try again.
With the pl2303 the serial monitor does not show nothing too.
