ESP-01 ESP8266 Serial WIFI Wireless Transceiver Module

The ESP‑01 is a compact and cost-effective Wi‑Fi module based on the ESP8266 chip. Featuring a simple serial interface (UART), it enables wireless communication for microcontroller projects, IoT devices, and home automation systems. Its minimal pinout and small form factor make it ideal for embedding in space-constrained designs.

Features:

• Full TCP/IP stack with integrated Wi‑Fi (802.11 b/g/n)

• Easy UART control using AT commands

• Supports deep sleep mode for low-power applications

• 1 MB flash memory for firmware and scripts

• Compact size ideal for embedded use

• On-board PCB antenna

• GPIO0 and GPIO2 provide basic I/O control
