ESP8266 Adapter Plate
This ESP8266 Adapter Plate is an Adapter PCB Plate for ESP-07, ESP-08, ESP-12E ESP8266 SMD ESP8266 Module. These SMD ESP8266 modules have an unfriendly pin pitch. But by use of this adapter PCB, you can solder ESP-07, ESP-08 or ESP-12E modules and can use your favorite ESP8266 SMD modules on breadboards or on perforated boards.
ESP8266 adapter plate compatible with the ESP07, ESP08, and ESP12. Because soldering the ESP modules is not always easy, this adapter plate is available. The WiFi module can be soldered to the PCB, wherein they are connected to connection points clearly indicated by headers.
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.
