This ESP8266 Adapter Plate is an Adapter PCB Plate for ESP-07, ESP-08, ESP-12E SMD Module. These ESP8266 SMD modules have an unfriendly pin pitch. But using this adapter PCBwiil make it easier, you can solder and use your favorite ESP8266 SMD modules on like any wemos or Nodemcu boards.ESP8266 adapter plate compatible with the ESP07, ESP08, and ESP12. The WiFi module can be soldered to the PCB, connection points are clearly indicated on the board.

On the bottom layer, there is a land-pattern for a 3.3V regulator. To use 3.3V regulator you will need to desolder 0 Ohm jumper resistor R1. The VCC pin then becomes 4.5V to the 9V power input.

Features :

It features reserved land-pattern for the 3.3V regulator

It has Pinouts on the top layer in black color.

Compatible with Latest ESP-12F ESP8266 Wifi Module

It includes a 10K pull-up resistor populated on PCB.

So you have an ESP-12F and want to use it in a project, well you got it, the best way is to use a 12x adaptor plate. 

in this tutorial, you will learn how to solder the esp8266 adaptor plate to the ESP-12F and how to program the ESP-12F using it.

WiFi - ESP8266 ESP-12F.

Tin the ESP-12F adaptor plate with solder, then solder the ESP-12F into it.

Place 2 female headers into a breadboard, place the adaptor plate onto the headers then solder the pins into place.

This is what the adaptor plate looks like with the headers and ESP-12F soldered in place.

Testing the completed board. The blue LED is the ESP-12F running the blink sketch.
