hello, my arduino leonardo pro micro after trying to make a project between arduino mega and leonardo through serial, when I disassembled to carry out another project, it stopped being recognized by ide, but when I press the reset button, it returns to does not work, I tried with another PC and the same thing hap
There is such a thing?
Can you show a wiring diagram of the circuit that burned your Pro Micro?
How are you using the board now? Is it connected to any external hardware?
doesn't look like anything burnt
now, I'm using it connected directly from the computer
the RX and TX leds do not light up
no, I'm trying to send an empty code, straight from the IDE, but it ''connects'' when it resets and then disconnects. 
it worked, the problem was only the bootloader!!!
It's either a Leonardo or a Pro Micro 
Your image in post #3 shows a (clone) Pro Micro.
So how did you solve it?
Although not impossible, I doubt that it was the bootloader. In my experience, it's 99.9% of the time something in your sketch that prevents the board from being recognised or from being able to upload.
You know the double-tap reset trick to 'activate' the bootloader?
I know yes, but this command had crashed, it didn't come out just bootloder.
It's actually the 2 Arduinos together.
