ESP8266 WiFi Serial Transceiver Module - 1MB Flash

Note This is the latest version of ESP8266 Serial Transceiver Module. There is not much change from the old version, just improved the Flash to be 1M and changed the color to the black, which is much cooler than the blue. We just released a tutorial for this module. Key Features Perfect choice for wifi enabled iot projects Abundant community resources around ESP8266 Upgrade 1M Flash High degree of on-chip integration Powerful on-board processing and storage capacities Description The ESP8266 Serial WIFI Wireless Transceiver Module is a system on a chip (SOC) Wi-Fi microchip for Internet of Things (IoT) applications produced by Espressif Systems. The ESP8266 module enables microcontrollers to connect to 2.4 GHz Wi-Fi, using IEEE 802.11 bgn. It can be used with ESP-AT firmware to provide Wi-Fi connectivity to external host MCUs, or it can be used as a self-sufficient MCU by running an SDK. The module has a full TCP/IP stack and provides the ability for data processing, reads and controls of GPIOs. Given its low cost, small size and adaptability with embedded devices, the ESP8266 is now used extensively across IoT devices. It is always a popular choice for IoT developers and manufacturers. It has many GPIOs. With the help of a SDK and various libraries, you can build your own firmware and use these GPIOs as arduino pins, and it makes external microcontrollers unnecessary. SDKs There is now a wide range of software development kits (SDKs) available, enabling developers to program the chip directly without using a separate MCU. Espressif provides two official SDKs for use with ESP8266, which are: A FreeRTOS based SDK A Non-OS SDK Application The ESP8266 modules are commonly found in the following IoT devices: Smart security devices, including surveillance cameras and smart locks Smart energy devices, including HVACs and thermostats Smart industrial devices, including Programmable Logic Controllers (PLCs) Smart medical devices, including wearable health monitors Other applications: Smart Power Plug home automation mesh network industrial wireless control baby monitor webcam sensor networks wearable electronic products security ID tag wireless positioning system signal ....
