ESP8266 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. When ESP8266 hosts the application, and when it is the only application processor in the device, it is able to boot up directly from an external flash. It has integrated cache to improve the performance of the system in such applications, and to minimize the memory requirements. Alternately, serving as a Wi-Fi adapter, wireless internet access can be added to any microcontroller-based design with simple connectivity through UART interface or the CPU AHB bridge interface. ESP8266 on-board processing and storage capabilities 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. With its high degree of on-chip integration, which includes the antenna switch balun, power management converters, it requires minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area. Sophisticated system-level features include fast sleep/wake context switching for energy-efficient VoIP, adaptive radio biasing for low-power operation, advance signal processing, and spur cancellation and radio co-existence features for common cellular, Bluetooth, DDR, LVDS, LCD interference mitigation.


Features:

  • SDIO 2.0, SPI, UART
  • Integrated RF switch, balun, 24dBm PA, DCXO, and PMU
  • Integrated RISC processor, on-chip memory and external memory interfaces
  • Integrated MAC/baseband processors
  • Quality of Service management
  • I2S interface for high fidelity audio applications
  • On-chip low-dropout linear regulators for all internal supplies
  • Proprietary spurious-free clock generation architecture
  • Integrated WEP, TKIP, AES, and WAPI engines

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. If you are looking for the breakout board with on board regulator and standard header compatibility, 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. 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.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.


Specifications:

  • NodeMCU is the fast leading edge low cost technology to WiFi
  • Modern high level mature LUA based technology
  • It is an integrated unit with all available resources on board
