#75393 yes, agreed, buy a separate power supply capable of 1A (300ma is sufficient if its a very good power supply) for powering the ESP and use only the TX - RX - Ground pins of the FT232RL (don't connect V+). Make sure everything is 3.3V @ the ESP

#75394 So, the following configuration is sufficient for boot-loading and running?

Esp…..Serial
TX0…..RXD
RX0…..TXD
GND…..GND
VCC to external power supply….. VCC left unconnected
REST…..RST
GPIO0…..DTR

#75395 But here Esp VCC has been connected to external 3.3V power supply. Then why VCC has also been connected to the same 3.3V of the external source??
