ESP-M4 Wireless WiFi Module ESP8285 Serial Port Transmission Control Module E... (TYPE2: ATFIRMWARE)

SELECTED OPTION:
TYPE2: ATFIRMWARE

Product description: ? The core processor of the ESP-M4 module uses the cost-effective chip ESP8285. The chip integrates an enhanced version of Tensilica's L106 Diamond Series 32-bit core processor in a smaller package with on-chip SRAM. The ESP8285 has a full Wi-Fi network function, which can be used independently or as a slave to other host MCUs. When the ESP8285 hosts an application, it can be launched directly from external Flash. The built-in cache helps improve system performance and optimizes the storage system. In addition, the ESP8285 can be used as a Wi-Fi adapter via the SPI/SDIO interface or I2C/UART port for any microcontroller-based design. The ESP-M4 module supports the standard IEEE 802.11 b/g/n/e/i protocol and the complete TCP/IP protocol stack. Users can use this module to add networking capabilities to existing devices or to build separate network controllers. The ESP-M4 module offers maximum practicality at the lowest cost, providing unlimited possibilities for Wi-Fi functionality to be embedded in other systems.
