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.
