ESP-01 ESP8266 Serial WIFI Wireless Transceiver Module
The ESP-01 ESP8266 Serial WiFi Wireless Transceiver Module is a versatile System on Chip (SoC) that includes a TCP/IP protocol stack, enabling seamless WiFi network access for microcontrollers. It can either host applications or manage Wi-Fi networking functions for other processors.
Pre-programmed with an AT command set, the ESP8266 allows for easy integration with Arduino devices, providing extensive WiFi capabilities similar to those of a dedicated WiFi shield. Despite its compact size, it offers robust processing and storage capabilities, facilitating smooth connections with sensors and other peripherals via GPIO pins.
This module features high on-chip integration, requiring minimal external components, making it a cost-effective solution for various applications. Its self-calibrated RF ensures reliable performance under different operating conditions without the need for additional RF components.
Backed by a large and active community, the ESP8266 module offers a wealth of resources and tutorials, making it a popular choice for IoT projects. Notably, this version of the ESP8266 module has an increased flash memory size, expanding from 512k to 1MB.
Please note that the ESP8266 Module requires an external logic level converter for 5V to 3.3V logic level conversion and should not be powered directly from a 5V development board.
