[SOLVED] ESP8266-01S does not work on serial
Posted: Fri Jan 29, 2021 3:23 pm
I tried now multiple ESP01, multiple serial converter and usb cables, but nothing works.
I've wired it like that:
As indicated by the "verified", I've checked it indeed is outputting 3.3V on VCC and I've verified it is a 10k resistor.
I've tried to wire the CH_PD and GPIO0 directly to VCC as some other instructions show, but that didn't work either.
What am I doing wrong? it blinks for a second sometimes and then stops.
Thanks for any input!
I've wired it like that:
Code: Select all
(Left ESP) (Right Serial Converter)
RX => TX
TX => RX
CH_PD => 10k Resistor (verified) => VCC (3.3V - verified)
GPIO0 => 10k Resistor (verified) => VCC (3.3V - verified)
GND => GND
VCC => VCC
