ESP8266 ESP-01 RGB LED Controller Module

ESP8266 ESP-01 RGB LED Controller ModuleThis compact and powerful adapter board seamlessly integrates with the ubiquitous ESP8266 ESP-01 Wi-Fi module, effectively transforming it into a fully capable RGB LED controller optimized for Internet of Things (IoT) applications. The module incorporates the necessary current-driving transistors or MOSFETs, allowing it to directly control common anode or common cathode RGB LED strips within specific current limits, consequently drastically simplifying the hardware required for creating intelligent, wirelessly controlled lighting. Designed for plug-and-play simplicity, it features a dedicated socket for the ESP-01 and breaks out the essential General Purpose Input/Output (GPIO) pins required for Pulse Width Modulation (PWM) signaling.

Key Features

• Dedicated ESP-01 Socket: Ensures non-soldered, secure integration of the ESP-01 module, simplifying assembly and maintenance.
• Integrated Output Drivers: Includes Mosfets or transistors capable of sinking/sourcing the current required for three independent color channels.
• Triple RGB Control Channels: Provides three separate outputs (R, G, B) compatible with the PWM output from the ESP-01 for full-spectrum control.
• Onboard Reset Button: Features a tactile momentary switch connected to the RST pin for easy module rebooting or firmware flashing initiation.
• Wide Power Input Support: Accepts a regulated 5V DC supply, ensuring stable operation for both the control logic and the LED drivers.
• Compact Form Factor: Optimized size for placement within small, constrained volumes typical of lighting projects.

Technical Specifications

• Input Operating Voltage (VCC): 5V DC (Required for the module’s stable operation).
• Logic Voltage (ESP-01): 3.3V (Provided by an onboard low-dropout regulator).
• Maximum Output Current per Channel: Typically rated for ≈1A to 3A, depending on the specific MOSFETs used, therefore consult the board documentation for exact load limits.
• Controllable Channels: 3 (Red, Green, Blue) for 24-bit color depth control (when driven by 8-bit PWM per channel).
• Control Signal Type: Digital PWM (TTL Logic Level).
• Networking Standard: 802.11 b/g/n (Via the plugged-in ESP-01 module).
• LED Strip Compatibility: Compatible with both Common Anode and Common Cathode configurations, though typically wired for Common Anode.

Mechanical Specifications

• PCB Material: Standard FR4 substrate, often blue in color.
• Mounting: Includes a pre-drilled hole for mechanical fastening to a surface or enclosure.
• Assembly: Utilizes high-density SMT for passive components and drivers to minimize board size.
• Connectors: Features pin headers or wire leads for input power and output load connections.

Dimensions

• Overall Module Size: ≈35mm length × 25mm width × 10mm height (Excluding connecting wires).
• Mounting Hole Diameter: ≈3mm.

Pinout and Wiring

• VCC (Input Power): Receives the main 5V DC power supply.
• GND (System Ground): Connects to the common ground of the power supply and LED strip.
• RGB Output: Four terminals provide the R, G, B, and common connection points for the external LED load.
• ESP-01 Pins Used: GPIO0 and GPIO2 are often multiplexed to provide the three required PWM signals.
