DESCRIPTION

NodeMCU Lua ESP8266 ESP-12E Serial WiFi Internet of Things Development Board

PROJECT  DESCRIPTION:

        Node MCU is an open source IoT platform. It uses the Lua scripting language. It is based on the eLua project, and built on the ESP8266 SDK 0.9.5. It uses many open source projects, such as lua-cjson, and spiffs. It includes firmware which runs on the ESP8266 Wi-Fi SoC, and hardware which is based on the ESP-12E module.

ESP-12E is designed and developed by Shenzhen Doctors of Intelligence & Technology (SZDOIT) based on the Ultra-low power consumption UART-WiFi ESP8266, which is specially for mobile devices and application of IoT (Internet of Things). Now, ESP-12E is widely applied to internet, communication in local area, intelligent home, industrial control, handed-devices, and etc.ESP-12E DevKit is used the design of on-board antenna and encapsulated by 2.54 direct insertion. It is very convenient to debug and install device.

In ESP-12E DevKit, Hardware API operation is encapsulated by Lua language, which can avoid the hardware difficulty for sorfware engineers, and then can speed the develop of products.This is just the ESP-12 chip.

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.
 

You can program it to run C code as well as Lua code. You can get started programming with the ESP8266 either with the Arduino Uno or with the CP2102 USB To UART Serial converter

Add Internet to your next project with an adorable, bite-sized WiFi microcontroller, at a price you like! The ESP8266 processor from Espressif is an 80 MHz microcontroller with a full WiFi front-end (both as client and access point) and TCP/IP stack with DNS support as well.  We do sell these on a breakout, but maybe you wanna just put this in your own project PCB.

As of Sept 3rd, we are shipping the ESP-12E version which has the SPI flash pads brought out on the bottom row. Note that you cannot use them for GPIOs or anything, they're there so you can program the FLASH chip only.

These modules are very easy to hand solder, with big pads! We have this part in the Adafruit Eagle library (ESP12) - the extra pads don't appear but they are not usable anyways.

The actual connections will depend on the board you have and the USB to serial adapter you are using.

This is the ESP-12 with SPI and extra GPIO pins along the bottom of the PCB (which explains the model number ESP12E). Note that the pinout labels on the PCB may be incorrect, please see the diagram in the images above - and although labelled as such you cannot use GPIO9 and 10 on this board.

Please note that there is no "formal" structure for ESP8266-based software environments, and everything provided is by the community of users and not the creator or suppliers of ESP8266-based hardware. Due to this we do not offer detailed support for coding and only offer a hardware warranty.

No doubt you read about the super-cheap WiFi module on various websites - and now it's here, in Australia from Tronixlabs - ready to ship. Unlike our other ESP8266 module, this one is all mounted on a tiny board along with a PCB antenna. All the I/O pins are broken out and you can design your PCB around this, or simply nudge some inline connectors to the PCB for a quick solder job, or solder some tiny tiny wires into the holes. Furthermore this ESP-12E variant has the "metal can" for extra shielding.

Note - this is a 3.3V part. 5V will kill it. So don't directly connect it to your Ardiuno Uno or similar board! Get yourself a level converter instead.

We also have the matching SMD breadboard adaptor to make life easier.

Furthermore, this ESP12-E has extra I/O and SPI pin interfaces - MTDO, MTDI, SD_3, MTMS, MTCK, SD_2.

This is a WiFi serial transceiver module, based on ESP8266 SoC. The SOC has Integrated TCP/IP protocol stack. To get started and for a couple of tutorials, see the "Resources" links below. ESP8266 is a highly integrated chip designed for the needs of a new connected world.
