Saludos cordiales compañeros del foro, necesito de su ayuda estoy iniciando con el modulo esp8266-01s el tema es que realizo la conexion como se indica, con un convertidor USB-TTL con chip PL2303, el tema es que inicialmente al conectar el GPIO0 a Low no me arrajaba ninguna comunicacion ni con el arduino IDE y con el programa Putty, luego conecte el pin GPIO2 a Low (GND) y si comunica tanto al Ide de arduino como al Putty pero he probado todas las velocidades de conexion solo lee basura, pense que podria ser la alimentacion del convertidor de 3,3 VCC pero luego de conectarlo con una fuente externa y medirla me da 3,35 VCC y sufiente amperaje y sigue igual alguien me pude ayudar???

Here is a Bing translation of the post, a bit lacking in clarity!:-
Greetings fellows of the forum, I need your help I am starting with module esp8266-01s the theme is that I perform the connection as indicated, With a USB-TTL converter with PL2303 chip, the point is that initially when connecting the GPIO0 to Low I did not root any communication with e-app or the Arduino IDE and the Putty program, then connect the GPIO2 pin to Low (GND) and if it communicates to both the Arduino Ide and putty but I tested all the connection speeds only reads garbage, I thought it could be the power supply of the 3.3 VDC converter but after connecting it to an external source and measuring it gives me 3.35 VDC and its own amperage and still someone could help me???
@electronic2021 you say you are getting garbage. Have you tried the 74880 baud rate? Why, see here:-
Why does ESP8266 show 'Garbage' characters?
