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