WiFi add-on module – ESP-01

The ESP-01 ESP8266 Serial WiFi Transceiver Module is a powerful, low-cost solution for adding wireless connectivity to your electronics projects. Based on the ESP8266 chip, this module operates on the 2.4GHz frequency band and supports IEEE 802.11 b/g/n WiFi protocols. It features an integrated TCP/IP protocol stack, allowing microcontrollers to connect to WiFi networks via a simple serial (UART) interface. With its compact form factor and minimal pin count, the ESP-01 is perfect for space-constrained applications such as IoT devices, home automation, remote sensor monitoring, and smart control systems. It can function as both a WiFi client and an access point. The module requires a 3.3V power supply and is widely compatible with popular development boards like Arduino Uno, Nano, and ESP8266-based systems. Choose the ESP-01 for a reliable, easy-to-implement wireless solution that accelerates your prototyping and product development.
