## Description

WiFi module based on ESP8266, ideal for quickly connecting Arduino and IoT projects to the 2.4GHz network, interfaces simply via serial UART at 115200 bps, runs on 32-bit architecture with 5V power supply and 3.3V logic, includes PCB antenna for compact installation and supports WEP, WPA, WPA2 security for reliable transmissions.
The ESP-15F module, compatible with Arduino and other development boards, is a wireless communication module that uses the Wi-Fi standard for data transmission. It is based on the ESP8266 microcontroller with a 32-bit architecture and works with a 5-volt supply voltage.
The module is designed to be connected to a device via the serial port. It has a UART interface and supports transfer rates of 115200 bits per second. It can be used in a variety of applications that require wireless connectivity, such as building automation, controlling IoT devices and more.
The module offers support for WEP, WPA-PSK/WPA2-PSK security protocols, which makes it suitable for applications that require high security. It also has low energy consumption.
The board comes with a connection interface with a PH2.54 plug, (the Tata plug with the necessary wires are not included in the package) 4 pins that allow access to the VCC, GND, RX and TX pins. A total of 8 pins are available on the board.
The antenna is integrated directly into the PCB, without the need to add an external one.
