Olimex ESP8266 module – MOD-WIFI-ESP8266-DEV

Hardware

I need a bigger flash and a breadboard friendly board. Quick research lead to the following variants, beside soldering a bigger flash on the ESP-XX series modules.

  1. NodeMCU board’s that have bigger flash and fit on a breadboard but have regulators and usb 2 serial on them.
  2. ESP-XX module with adapter,  don’t like .
  3. MOD-WIFI-ESP8266-DEV

And the winner is Olimex’s – MOD-WIFI-ESP8266-DEV .

i got some of them:
