— a significant improvement over the standard D1 Mini with larger flash memory options (4MB or 16MB) and an optional external antenna connector for extended WiFi range. The ESP8266 is the most widely used WiFi SoC in the maker and IoT community, combining a 32-bit Tensilica L106 processor with 802.11 b\/g\/n WiFi in a single chip. The NodeMCU Lua firmware is pre-loaded, and the board is fully compatible with the Arduino IDE via the ESP8266 Arduino core — enabling Arduino-style programming with WiFi connectivity for smart home,

is the difference between 4MB and 16MB flash?\u003c\/strong\u003e\u003cbr\u003eA: 4MB flash is sufficient for most Arduino sketches and NodeMCU Lua scripts. 16MB flash is recommended for projects using SPIFFS (file system), large web server assets, OTA updates, or complex firmware. The 16MB version also supports larger Lua scripts and more stored data.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is the external antenna version better for all applications?\u003c\/strong\u003e\u003cbr\u003eA: The external antenna version provides better range through walls and over longer distances. For applications within 10–15 metres of the router with no obstructions, the PCB antenna version is adequate. For basement installations, metal enclosures, or long-range applications, choose the external antenna version.\u003c\/p\u003e\n\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1× Mini D1 PRO ESP8266 WiFi Development Board (flash size and antenna option as selected)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Keszoox","offers":[{"title":"16MB","offer_id":46985498198251,"sku":"14:4044226#16MB","price":25.24,"currency_code":"USD","in_stock":true},{"title":"4MB","offer_id":46985498231019,"sku":"14:351074#4MB","price":22.8,"currency_code":"USD","in_stock":true},{"title":"16MB Add the antenna","offer_id":46985498263787,"sku":"14:350852#16MB Add the antenna","price":29.64,"currency_code":"USD","in_stock":true},{"title":"4MB Add the antenna","offer_id":46985498296555,"sku":"14:1202#4MB Add the antenna","price":25.44,"currency_code":"USD","in_stock":true},{"title":"antenna","offer_id":46985498329323,"sku":"14:201659813#antenna","price":7.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/1005\/8731\/files\/mini-d1-pro-esp8266-wifi-nodemcu-lua.webp?v=1761284460"},{"product_id":"inmp441-mems-omnidirectional-microphone-module-with-i2s-interface-for-esp32","title":"INMP441 MEMS Omnidirectional Microphone Module with I2S Interface for ESP32","description":"\u003ch1\u003eSPECIFICATIONS\u003c\/h1\u003e\u003cp\u003e\u003cspan\u003eApplication\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003estandard\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eBrand Name\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003eKeszoox\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eChoice\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003eyes\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eCondition\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003eNew\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eDissipation Power\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003estandard\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eHigh-concerned chemical\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003eNone\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eModel Number\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003eINMP441\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eOperating Temperature\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003estandard\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eOrigin\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003eMainland China\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eSupply Voltage\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003estandard\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eType\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003eModule\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eis_customized\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003eYes\u003c\/span\u003e\u003c\/p\u003e\u003cdiv class=\"detailmodule_html\"\u003e\u003cdiv class=\"detail-desc-decorate-richtext\"\u003e\n\u003cdiv\u003e\n Product Description:\n\u003c\/div\u003e\n\u003cdiv\u003e\n The INMP441 is a high performance, low power, digital output, omnidirectional MEMS microphone with bottom port.

For SPI at 4MHz or higher, use a dedicated push-pull level shifter (TXS0108E, SN74LVCC3245A) instead.

You cannot plug ESP-12E directly into the holes, but you can solder it flat onto the board surface using the castellated pads, or use a 2mm-to-2.54mm adapter.
