CANdle™ – CAN-Enabled Addressable LED Controller & Voltage Regulator

The CANdle™ from CTR Electronics is a versatile, high-efficiency DC voltage regulator and LED controller designed for FRC robotics, competitive robotics, and automation applications. Equipped with eight onboard individually addressable RGB LEDs, CANdle™ supports a variety of built-in animations and allows direct LED control via CAN bus, CAN FD, or WS2812B pulse-train, enabling complex visual effects without additional wiring.

This robust device also provides full voltage and current monitoring, short-circuit, overcurrent, and thermal protections, ensuring safe operation even in demanding robotics environments. Its capability to daisy-chain multiple devices from a single power source makes it ideal for multi-device LED and voltage control setups on robots or automation platforms. CANdle™ is fully Phoenix 6-compatible, unlocking advanced high-performance control features for FRC teams and professional robotics projects.

Key Features

• Eight onboard individually addressable LEDs with multiple built-in animations (Larson, rainbow, twinkle, color fades, and more) — no extra wiring required
• Control via CAN bus/CAN FD or WS2812B pulse-train; supports external 12V or 5V addressable LED strips and high-side duty cycle modulation for downstream 12V systems
• Auto-detects input type for plug-and-play operation; CAN FD compatible with Phoenix and Phoenix Pro for advanced control
• 5V output powers peripherals (Jetson Nano, Raspberry Pi, etc.)
• Comprehensive protection: reverse input power, short-circuit/overcurrent, and thermal safeguards with real-time voltage and current monitoring
• Polycarbonate housing with electrically isolated heatsink for safe robot-frame mounting
• Robust bootloader with wireless field firmware upgrades — no physical buttons needed

Product Benefits

• Simplified LED Integration: Onboard LEDs and WS2812B compatibility reduce wiring complexity and installation time
  
• Advanced Visual Feedback: Multiple animations and direct control allow teams to communicate status, alerts, or effects visually
  
• Safe & Reliable Operation: Built-in protections and monitoring ensure long-term reliability in high-performance robotics
  
• Flexible Power Management: Supports 5V and 12V systems, powering both LEDs and small peripherals
