Features:
- WiFi Connectivity: Directly connects to WiFi routers, ideal for smart home and IoT applications.
- ESP-12 Module: Offers extensive GPIO access and flexibility compared to other ESP8266 variants.
- Programming Options: Compatible with Arduino IDE and NodeMCU (LUA), allowing standalone operation without an external MCU.
- On-Board Components:
- LDR (Light Dependent Resistor): Enables ambient light detection.
- WS2812 RGB LED: Fully programmable LED for visual feedback and effects.
- Tactile Buttons: Includes 3 buttons (1 on Witty board, 2 on CH340 board) for interactive control.
- CH340 Micro USB Interface: Simplifies power and programming through USB.
- Energy-Efficient Design: Features antenna switch balun, power management converter, and supports low-power sleep modes for efficient energy usage in VoIP and other wireless applications.
- Multiple Operating Modes: Supports AP (Access Point), STA (Station), and AP+STA hybrid modes.
- Compact Dimensions: Measures only 24mm x 16mm, ideal for space-constrained applications.
- Micro USB Connectivity: Provides an easy interface for power and programming.
Specifications:
- Microcontroller: ESP8266 (ESP-12 Module)
- WiFi Standard: IEEE 802.11 b/g/n
- Voltage: 3.3V logic and power
- Interface: UART (Rx, Tx), GPIO
- Dimensions: 24mm x 16mm
- Operating Modes: AP / STA / AP+STA
Pinout Overview:
The ESP8266-03 exposes several GPIO pins and communicates over serial UART (Rx, Tx). Use 3.3V logic only—direct 5V connection may damage the module.
Applications:
- Home automation systems
- Wireless sensor nodes
- WiFi-enabled lighting systems
- IoT prototyping and development
- Environmental monitoring
