# WLED Driver Board (ESP32-C3 / D1 Mini Compatible)
A compact LED controller board designed to simplify running WLED using either an ESP32-C3 module or a Wemos D1 Mini.
This board integrates power regulation and signal routing to reduce wiring and external components.
---
## Features
- Supports ESP32-C3 (recommended)
- Compatible with Wemos D1 Mini (ESP8266)
- Designed for WLED firmware
- Input voltage up to 28V DC
- On-board 3.3V step-down regulator
- Works with addressable LED strips (WS281x, etc.)
- Compact and easy to integrate
---
## Power
- Input Voltage: up to 28V DC
- On-board regulator provides ~4.8V for the controller
NOTE:
- LED strips are powered directly from the input voltage
- The board does NOT regulate LED voltage
Make sure your LED strip matches your supply voltage (5V, 12V, 24V, etc.)
---
## Supported Controllers
### ESP32-C3 (Recommended)
- Lower power consumption
- Better performance than ESP8266
- Often includes native USB
### Wemos D1 Mini (ESP8266)
- Drop-in compatible
- Fully supported by WLED
- Good for simple or low-cost builds
---
## WLED Setup
1. Solder your controller (ESP32-C3 or D1 Mini)
2. Connect power supply (max 28V)
3. Connect LED strip:
- V+
- GND
- DATA
4. Flash WLED firmware
5. Configure GPIO in WLED web interface
---
## Typical GPIO
ESP32-C3:
- LED Data: configurable (example GPIO2)
D1 Mini:
- LED Data: D4 (GPIO2)
GPIO can be changed in WLED settings.
---
## Connections
### Power Input
- VIN
- GND
### LED Output
- V+ (same as input)
- GND
- DATA
### Controller Headers
- ESP32-C3 or Wemos D1 Mini
---
## Design Notes
- 3.3V regulator only powers the controller
- LED power is passed directly from input
- Keep data wire short for stability
- Level shifting may be needed for long runs
---
## Safety
- Do NOT exceed 28V input
- Check polarity before powering
- Use proper wiring for high current loads
- Ensure adequate cooling if running large LED setups
---
## Use Cases
- LED strips (WS2812B, WS2815, SK6812)
- Ambient lighting
- Home automation
- 12V / 24V LED installations
