ESP8266 ESP-12 Remote Serial Port WIFI Transceiver

UK STOCK, UK SELLER

The ESP8266 is one of the most talked about modules on the internet. There
are so many applications this little unit can be put to, only limited by
your imagination.
ESP8266 is a highly integrated chip designed for the needs of a new
connected world. It offers a complete and self-contained Wi-Fi
networking solution, allowing it to either host the application or to
offload all Wi-Fi networking functions from another application
processor.

ESP8266 has powerful on-board processing and storage capabilities
that allow it to be integrated with the sensors and other application
specific devices through its GPIOs with minimal development up-front and
minimal loading during runtime. Its high degree of on-chip integration
allows for minimal external circuitry, and the entire solution,
including front-end module, is designed to occupy minimal PCB area.

Great NEWS

The ESP8266 ESP-12 that I provide will have firmware v0.9.5.2 AT Baud Rate 115200
When you send AT+GMR your ESP8266 ESP-12 device will respond with the version details as follows:
AT+GMR
AT version:0.21.0.0
SDK version:0.9.5
Please note that the SDK version displays 0.9.5 as apposed to 0.9.5.2
***************************************************************************************


The ESP8266 ESP-12 has the following pad outputs, Pitch distance is 2mm not not 2.54mm



Please note, that the silk screen print, on the module has the GPIO4 and GPIO5 labeled the wrong way, please follow the pin layout as above

Please also see my other ESP8266 devices as there are many types, offering different pin-out functions

THIS ITEM WILL BE FULLY TESTED PRIOR TO DESPATCHING (DO NOT EXCEED OPERATING
VOLTAGE), I will ensure that the firmware version is v0.9.5.2
I will check AT commands are responding and connect to a wireless router.
I will also connect Tx and Rx to a Microcontroller and test logging
onto a wireless router and transmit and receive data. I will therefore
not accept that the item has arrived as non-functioning.
