3pcs ESP-F1 Wireless WiFi Module ESP8266 Serial WiFi Module Compatible with ESP-07S

Features: ESP-F1 module core processor uses high cost performance chip ESP8266EX. The chip integrates the industry-leading Tensilica's L106 ultra-low power 32-bit micro MCU with 16-bit streamlined mode, 80 MHz and 160 MHz main frequency support and RTOS support in smaller size packages. ESP8266EX has a complete Wi-Fi network function, which can be used independently and run as a slave on other host MCUs. When ESP8266EX is applied independently, it can be booted directly from external Flash. The built-in cache memory is helpful to improve the system performance and optimize the storage system. In addition, ESP8266EX can be used as Wi-Fi adapter only through SPI/SDIO interface or I2C/UART interface, and can be applied to the design of any microcontroller. ESP-F1 module supports standard IEEE802.11 b/g/n/e/i protocol and complete TCP/IP protocol stack. Users can use this module to add networking functions to existing devices, or to build independent network controllers. ESP-F1 module provides maximum practicability at the lowest cost, and provides infinite possibilities for Wi-Fi function to be embedded in other systems.
