ESP8266 series modules are a series of low-power UART-WiFi chip modules based on Espressif's ESP8266EX developed by Shenzhen Ai-Thinker Technology Co., Ltd., which can be easily developed for secondary development, access to cloud services, and realize mobile phones 3/4G global control anytime, anywhere, accelerate product prototype design.

The module core processor ESP8266 integrates the industry-leading Tensilica L106 ultra-low-power 32-bit micro MCU in a smaller package, with a 16-bit compact mode, the main frequency supports 80 MHz and 160 MHz, supports RTOS, and integrates Wi -Fi MAC/BB/RF/PA/LNA, onboard antenna. Support standard IEEE802.11 b/g/n protocol, complete TCP/IP protocol stack. Users can use this module to add networking functions to existing equipment, or build an independent network controller.

ESP8266 are high-performance wireless SoCs that provide maximum practicability at the lowest cost, and provide unlimited possibilities for Wi-Fi functions to be embedded in other systems.
