Key Features
- Full WiFi SoC: Complete 802.11 b/g/n WiFi stack with TCP/IP built into the ESP8266EX chip - no external WiFi IC required
- Dual Operating Modes: Use as a WiFi co-processor with AT commands over UART, or program it standalone as an independent microcontroller
- Ultra-Compact Form Factor: Measures just 24.8 x 14.3 mm, making it ideal for space-constrained embedded designs and wearable projects
- Arduino IDE Compatible: Fully programmable via Arduino IDE with the ESP8266 board package - use familiar libraries, syntax, and upload process
- Low Power Deep Sleep: Draws only ~10 uA in deep sleep mode, enabling battery-powered IoT sensor nodes with months of standby life
- Onboard PCB Antenna: No external antenna needed; provides reliable connectivity up to 100 meters in open environments
- Versatile Protocol Support: Handles HTTP, MQTT, TCP, UDP, and WebSocket protocols for virtually any IoT communication pattern
- 3.3V Logic Level: Direct interfacing with 3.3V microcontrollers; pair with a level shifter for 5V systems like Arduino Uno
