Espressif ESP8266 Serial Port WiFi Transceiver Module (ESP-05)
The Espressif ESP8266 Serial Port WiFi Transceiver Module (ESP-05) is a compact and versatile device designed to provide wireless Internet connectivity to any microcontroller platform, such as Arduino. With a simple pin layout and serial communication interface, it seamlessly integrates into projects, requiring only two wires (TX/RX) for connection. The module handles WiFi tasks independently, freeing up microcontroller code from unnecessary complexity. It features powerful on-board processing and storage capabilities, allowing it to interface with sensors and devices through GPIOs with minimal development overhead. Additionally, it supports control over SPI and UART interfaces, making it suitable for a wide range of applications. With AT command support, it enables easy connection to WiFi networks and TCP/IP communication without requiring a TCP/IP stack on the microcontroller.
