Product introduction:

  • The core processor of the ESP-F module uses the cost-effective chip ESP8266EX. This chip integrates the industry-leading Tensilica ’s L106 ultra-low-power 32-bit micro MCU in a smaller package, with a 16-bit reduced mode, the main frequency supports 80 MHz and 160 MHz, and supports RTOS. ESP8266EX has a complete Wi-Fi network function, which can be used independently or run as a slave on other host MCUs. When the ESP8266EX is used independently, it can be started directly from the external flash. The built-in cache memory helps improve system performance and optimizes the storage system. In addition, ESP8266EX can be used as a Wi-Fi adapter through SPI / SDIO interface or I2C / UART port, and can be applied to any microcontroller-based design.
  • ESP-F 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 capabilities to existing equipment or build stand-alone network controllers.
  • The ESP-F module provides maximum practicality at the lowest cost, providing unlimited possibilities for Wi-Fi functionality to be embedded in other systems.
