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.   \u003cbr\u003e    \u003cbr\u003e    \u003c\/a\u003e\u003ctable height=\"582\" style=\"border-collapse:collapse;width:594.02pt;\" width=\"792\"\u003e     \u003ccolgroup\u003e      \u003ccol width=\"119\"\u003e      \u003ccol width=\"250\"\u003e      \u003ccol width=\"423\"\u003e     \u003c\/colgroup\u003e     \u003ctbody\u003e      \u003ctr height=\"24\"\u003e       \u003ctd class=\"et2\" height=\"24\" style=\"font-size:\" width=\"119\"\u003e Classification\u003c\/td\u003e       \u003ctd class=\"et3\" height=\"24\" style=\"font-size:\" width=\"250\"\u003e Item\u003c\/td\u003e       \u003ctd class=\"et3\" height=\"24\" style=\"font-size:\" width=\"423\"\u003e Parameter\u003c\/td\u003e      \u003c\/tr\u003e      \u003ctr height=\"24\"\u003e       \u003ctd class=\"et4\" height=\"198\" rowspan=\"8\" style=\"font-size:\" width=\"119\"\u003e Wi-Fi\u003c\/td\u003e       \u003ctd class=\"et5\" height=\"24\" style=\"font-size:\" width=\"250\"\u003e Frequency?range\u003c\/td\u003e       \u003ctd class=\"et5\" height=\"24\" style=\"font-size:\" width=\"423\"\u003e 2.4G~2.5G(2400M~2483.5M)\u003c\/td\u003e      \u003c\/tr\u003e      \u003ctr height=\"27\"\u003e       \u003ctd class=\"et5\" height=\"78\" rowspan=\"3\" style=\"font-size:\" width=\"250\"\u003e Transmit?power\u003c\/td\u003e       \u003ctd class=\"et5\" height=\"27\" style=\"font-size:\" width=\"423\"\u003e 802.11b:?+20?dBm\u003c\/td\u003e      \u003c\/tr\u003e      \u003ctr height=\"27\"\u003e       \u003ctd class=\"et5\" height=\"27\" style=\"font-size:\" width=\"423\"\u003e 802.11g:?+17?dBm\u003c\/td\u003e      \u003c\/tr\u003e      \u003ctr height=\"24\"\u003e       \u003ctd class=\"et5\" height=\"24\" style=\"font-size:\" width=\"423\"\u003e 802.11n:?+14?dBm\u003c\/td\u003e      \u003c\/tr\u003e      \u003ctr height=\"24\"\u003e       \u003ctd class=\"et5\" height=\"72\" rowspan=\"3\" style=\"font-size:\" width=\"250\"\u003e Receiving?sensitivity\u003c\/td\u003e       \u003ctd class=\"et5\" height=\"24\" style=\"font-size:\" width=\"423\"\u003e 802.11b:?-91?dbm?(11Mbps)\u003c\/td\u003e      \u003c\/tr\u003e      \u003ctr height=\"24\"\u003e       \u003ctd class=\"et5\" height=\"24\" style=\"font-size:\" width=\"423\"\u003e\u003c\/td\u003e     \u003c\/tr\u003e    \u003c\/tbody\u003e   \u003c\/table\u003e","brand":"ZHIQIAN","offers":[{"title":"Default Title","offer_id":43932013953219,"sku":"ZHIQIAN-026717","price":393.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/wrsss.com\/products\/esp-m4-wireless-wifi-module-esp8285-serial-port-transmission-control-module-e-type2-atfirmware","provider":"Wrsss","version":"1.0","type":"link"}
