SZDOIT ESP-12F WIFI To Serial Port Wireless Transparent Transmission Wifi Module With ESP8266 Burning Fixture Development Board

Introduction:

• The ESP-12F WiFi module is a low-power, cost-effective embedded wireless network control module. It can meet the needs of IoT applications such as smart grid, building automation, security, smart home, and telemedicine.
• The module's core processor, the ESP8266, integrates the industry-leading Tensilica L106 ultra-low-power 32-bit micro-MCU in a small package with 16-bit thin mode, supporting 80 MHz and 160 MHz, supporting RTOS, and integrating Wi -Fi MAC/ BB/RF/PA/LNA, onboard antenna.
• The module supports the standard IEEE802.11 b/g/n protocol, a complete TCP/IP protocol stack. Users can use this module to add networking capabilities to existing devices or to build separate network controllers.
