ESP8266 tips and tricks
Last updated: 2017 Feb 12th
This is a list of tips and tricks for the ESP8266 module. I will update this page as I learn more about these chips. Pull requests are appreciated.
Where to look for help and support.
- ESP Community forums
- Gitter for ESP8266 - A group chat for the ESP8266 and the Arduino libary.
- Stackoverflow, and electronics.stackexchange are great for asking questions.
- Debugging ESP8266 Arduino - Instruction on how to set up the Arduino IDE to debug the ESP8266 Arduino libary.
- Andreas Spiess ESP8266 series. - Great youtube series of videos about the ESP8266. Highly suggested

Under normal operation the ESP8266 chip consumes around 70mA at 3.3v with spikes of 300mA. These spikes are really anying while building a power supply. A 1000-2200uF cap and reduce these spikes. Source: #47 Power Saving with ESP8266.
The ESP.deepSleep() function doesn't work unless there is a delay of 100 after this command.
ESP.deepSleep(1000*10000*3, WAKE_RF_DEFAULT) ; delay(100);
In deep sleep the ESP consumes around 0.06mA
