The adapter allows you to connect the antenna with the SMA 50 Ω female connector to the device with the MCX socket. The cord has a length of 13cm

Dual-band antenna operating in the 2.4 GHz or 5.8 GHz band. Works great with WiFi, Bluetooth or ZigBee. Uses the popular U.FL connector. SparkFun WRL-18087

Development board D1 Mini V3 with WiFi module ESP-8266 and 4 MB Flash memory. The module can be programmed from the Arduino IDE level. WeMos D1 Mini V3.x

Wi-Fi module based on the ESP8266 system - simplicity of use (communication through UART, supports AT commands), 3.3V power supply, support for WPA / WPA2 encryption - these features make the EPS8266 module applicable anywhere, where reliable and effective data transmission. The module is not equipped with an antenna, it should be attached using the U.FL connector. ESP-05

A small key ring with an RFID tag for systems operating at 125 KHz. Provides the ability to read and write a unique ID number

The Arduino Ethernet Shield 2 allows an Arduino Board to connect to the internet. It is based on the Wiznet W5500 Ethernet chip. The Wiznet W5500 provides a network (IP) stack capable of both TCP and UDP. There is an onboard micro-SD card slot, which can be used to store files for serving over the network. It is compatible with the Arduino Uno and Mega
