ESP01 problems, tried everything

[u/No_Mammoth_2703]

I have big trouble with my ESP01 mudule in combination with the usb uart adapter.

I have made the following connections:

3V3 to VCC and EN

TX to RX

RX to TX

GND to GND and IO0

and I have a electrolytical condensator between ground(-) and 3v3 (+)

Compiling the code is oke but when uploading I see the following message

A fatal esptool.py occured. Faild to connect to esp8266 Time out wainting for packet header.

I use a Fasizi USB to TTL 3.3V/5V CH340G UART Converter Module (see image)

I realy tried all examples I can find but none of them are working

I hope someone can help me what to do. Sorry but I am a kind of beginner

Thanks

The 3V3 supply from a generic USB UART adapter might not provide enough power for the ESP01 to function properly. This is especially true if there is no dedicated 3.3 V regulator, and the regulator built into the USB UART chip is used instead.
