    Description

    The ESP8266 01S is a low-cost WiFi module that allows microcontrollers to connect to a WiFi network and make simple TCP/IP connections using Hayes-style commands. It is an improved version of the popular ESP8266-01 module, featuring better stability and performance. The module is ideal for IoT (Internet of Things) applications, enabling devices to communicate wirelessly with the internet or local network.

    Key Features:

    • Integrated TCP/IP protocol stack
    • WiFi 802.11 b/g/n support
    • Built-in low-power 32-bit CPU, can also function as an application processor
    • 1MB of Flash memory
    • Supports AP (Access Point), STA (Station), and AP+STA modes
    • UART interface for easy integration
    • Wide range of GPIOs for connecting sensors and peripherals
    • Compact and lightweight design

    Technical Specifications:     

    • Microcontroller: Tensilica L106 32-bit RISC processor, running at 80 MHz
    • Operating Voltage: 3.0V to 3.6V
    • Flash Memory: 1MB
    • RAM: 50 kB
    • WiFi Standards: 802.11 b/g/n
    • Frequency Range: 2.4 GHz to 2.5 GHz
    • Data Rate: Up to 1 Mbps
    • UART Baud Rate: 9600 bps (default)
    • GPIO Pins: 2 (GPIO0 and GPIO2)
    • Operating Current: 70 mA (typical)
    • Deep Sleep Current: < 10 µA
    • Operating Temperature: -40°C to +125°C
    • Dimensions: 25mm x 15mm x 6mm

    Applications:

    • Internet of Things (IoT) devices
    • Home automation
    • Wireless sensor networks
    • Remote data logging
    • Smart appliances
    • Wearable technology
    • DIY electronics projects

    Usage:

    1. Connection:
      • Connect the VCC pin to a 3.3V power supply and GND to ground.
      • Connect the TX and RX pins to the UART interface of the microcontroller (with proper voltage level shifting if necessary).
      • Use GPIO0 and GPIO2 for additional control and sensor connections.
    2. Programming:
      • Use AT commands to configure and control the module via a serial interface.
      • Optionally, use the Arduino IDE or other compatible development environments to write custom firmware for the ESP8266.
    3. WiFi Configuration:
      • Configure the WiFi settings (SSID and password) using AT commands or custom firmware.
      • Establish TCP/IP connections for data communication with remote servers or local networks.
