2PCS ESP8266 Esp-01 Serial Wireless Wifi Transceiver Module With Keyestudio Packing Box For Arduino

This pack of two ESP8266 ESP-01 serial wireless Wi-Fi transceiver modules is an ideal choice for makers, students, and educators looking to add wireless connectivity to their microcontroller projects. These ultra-compact modules easily connect your hardware to local networks or the internet, making them perfect for IoT applications.

Compact IoT connectivity

This ultra-low-power UART-Wi-Fi pass-through module features an industry-leading small package size designed specifically for mobile devices and Internet of Things projects. It allows you to easily connect physical devices to a Wi-Fi wireless network for LAN or Internet communication.

Versatile wireless modes

The module supports the 802.11 b/g/n wireless standard and offers three flexible working modes: Station (STA), Access Point (AP), and a combined STA+AP mode.

Integrated TCP/IP stack

With a built-in TCP/IP protocol stack, this transceiver supports multiple TCP Client connections and can be controlled using various Socket AT commands.

Onboard processing and interfaces

Featuring a built-in 32-bit MCU, the module can double as an independent application processor. It supports UART and GPIO data communication interfaces for straightforward integration.

Low-power battery operation

Designed for ultra-low power consumption, this module runs on a single 3.3V power supply, making it highly suitable for battery-powered applications. It also supports Smart Link intelligent networking and remote over-the-air firmware upgrades.
