- Thu Jul 19, 2018 3:51 pm #77247 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

boudrate 115200 should work but if it doesnt, you can try 9600 till 115200 untill it works.
I don't know why but boudrade is sometimes different.
