Hello,
I want to use 2 esp12E with espnow.
When the esp is on the snap on programmer the esp now works fine (between Wemos and esp12e since i have only one programmer)
When i power the esp12e with battery then delivery fail.
what kind of battery ? ESP8266's are quite power hungry when transmitting and receiving WiFi
18650 holder module have used it with wemos d1 with no proplem.
Output power 3V up to 1A
Has power regulation circuitry.
Does not have power management circuitry. It requires 3.3V EXACTLY. You have to have other circuitry to regulate the power coming from your battery in order to power the ESP12E. If you have already connected the battery to the module once you have probably already burned it up.
Measured the output. Its 3.3V
Found the solution!
Ok, first of all admit i am a noob :l
Its the first time i use esp12e!
After researching abit found out i have to
Io15 ->GDN
EN -> 3.3V
Now works fine
