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 stackWiFi 802.11 b/g/n supportBuilt-in low-power 32-bit CPU, can also function as an application processor1MB of Flash memorySupports AP (Access Point), STA (Station), and AP STA modesUART interface for easy integrationWide range of GPIOs for connecting sensors and peripheralsCompact and lightweight designTechnical Specifications: Microcontroller: Tensilica L106 32-bit RISC processor, running at 80 MHzOperating Voltage: 3.0V to 3.6VFlash Memory: 1MBRAM: 50 kBWiFi Standards: 802.11 b/g/nFrequency Range: 2.4 GHz to 2.5 GHzData Rate: Up to 1 MbpsUART Baud Rate: 9600 bps (default)GPIO Pins: 2 (GPIO0 and GPIO2)Operating Current: 70 mA (typical)Deep Sleep Current: < 10 µAOperating Temperature: -40°C to 125°CDimensions: 25mm x 15mm x 6mmApplications:Internet of Things (IoT) devicesHome automationWireless sensor networksRemote data loggingSmart appliancesWearable technologyDIY electronics projectsUsage: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.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.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.AT Command Set//cdn.sparkfun.com/datasheets/Wireless/WiFi/Command Doc.pdf
