i bought esp 01 for the first time but could not figure out why its not working, i am using ftdi breakout board with 3.3v option my connection are following: esp-01 FTDI board VCC VCC(3.3v) GND GND TX RX RX TX CHP-PWD VCC RST VCC it is just not connecting to serial monitor of arduino ide one thing more i notice was that when i connect CHP-PWD to VCC the voltage between vcc and gnd of esp drops to 3.1v, first i thought it was a power supply issue but it tried separate power supply and even tried to connect resistor in between. but no luck
If you connect your esp-01 like this and press the RST button, you should see something in the terminal window. Try typing AT. If you get gibberish, try different baudrates.
