ESP8266-01 WiFi Transceiver Module (ESP-01)

The ESP8266-01 WiFi Transceiver Module, also known as ESP-01, is a small and affordable WiFi module designed for Internet of Things (IoT) applications. It features a low power consumption, built-in TCP/IP protocol stack, and support for various WiFi security protocols.

The ESP-01 module is based on the ESP8266 chip, which is a highly integrated WiFi SoC (System on Chip) that includes a microcontroller unit (MCU) and WiFi connectivity. The module operates on a single 3.3V power supply and communicates with a host device (such as a microcontroller) using a serial UART interface.

The ESP-01 module is commonly used in various IoT applications, such as home automation, smart appliances, and wireless sensor networks. It can be easily programmed using the Arduino IDE or other programming environments, and there are many libraries and examples available to help developers get started quickly.

It is important to note that the ESP-01 module has limited GPIO pins, which may require additional hardware (such as shift registers) for applications that require many input/output connections. Additionally, the module may have limited range and may require additional hardware (such as an external antenna) for applications that require long-range WiFi connectivity.
