The ESP8266MOD module is based on the ESP8266 chip. Works on the Wifi 802.11 b / g / n standard at 2.4 GHz. This device can be used as a converter for connecting the microcontroller to Wi-Fi or as an independent device, because it has a controller with FLASH and ROM memory. The ESP12 has 4MB of Flash memory. It is possible to program the module using LUA scripts, Arduino IDE or AT commands. Specification: 2.4 GHz frequency WiFi standard support: 802.11 b, g, n Modes of operation: AP (Access Point) STA (standalone) AP + STA Security: WPA WPA2 AT commands Pinout: 9 x GPIO - digital outputs / inputs 1 x ADC input - digital-to-analog converter 2 x UART (TX, RX) - for communication, e.g. with Arduino Supply voltage: 3.3V Power consumption at rest: Mon. 10u Mounting: SMD / THT: hole diameter: 0.9 mm Pins pitch: 2 mm It has an antenna on a PCB Shielded module Dimensions: 22 x 16 mm The adapter board allows you to connect a Wi-Fi module in the version ESP-12E as well as ESP-07 and ESP-08. The adapter changes the spacing of the pins from 2 mm to the standard 2.54 mm goldpin pitch, thanks to which the system can be plugged into, for example, a breadboard. The kit includes an adapter and 2.54 mm goldpin connectors (not soldered). The board has a place for soldering the voltage stabilizer, if it is used, the SMD R2 jumper should be desoldered. Set contains: - ESP8266MOD module - ESP adapter module - Male goldpin headers https://elecena.pl/product/22605340/esp8266mod-wifi-network-module-goldpin-header-adapter-board 2023-02-22 https://elecena.pl/product/22605340/esp8266mod-wifi-network-module-goldpin-header-adapter-board 2025-10-29
