Here's what I found about the maximum current on ESP8266 development board: ESP8266 operating current average value = 80mA Maximal output current from one GPIO pin is 12mA Total current for ESP8266 chip is sum of operating and GPIOs currents I've been working with Arduino too (projects to hire write...

Hi,

I've been using ESP8266 to send data to the server. I guess it should be done with the HTTP GET commands. Where should I indicate proxy's parameters on the ESP8266? I contacted Vicne (found the question on esp8266 forum last minute essay), but no answer so far.
Thanks.

I see that there's a price difference too: 02D has a higher price everywhere on the market. On the U and D modules, there is also an additional resistor. There's also an archived sample with the ESP-WROOM-02D and ESP-WROOM-02U writemyessay review if you are interested.

What have you tried so far?
