Professional-grade microcontroller-based system that intelligently splits combined brake/turn signal systems into separate outputs. Perfect for custom builds, classic car upgrades, and performance vehicle modifications.
Many vehicles use a two-wire system where each side combines turn signal and brake light functions. When you want separate amber turn signals and red brake lights, you need intelligent signal separation.
Not just another passive splitter - BTsplitter uses professional-grade components and intelligent firmware to deliver features no passive device can match
2-second brake persistence timer keeps brake lights on briefly after release. Programmable debouncing eliminates false triggers from electrical noise.
IRF9540 MOSFETs handle 23A continuous, 92A peak per channel. Powers any automotive lighting load - LED arrays, incandescent bulbs, even multiple strips.
PC817 optocouplers provide electrical isolation between 12V vehicle signals and 3.3V ESP32 logic. Protection from voltage spikes and noise.
ESP32-C3 microcontroller enables customizable timing, debouncing, and behavior. Update firmware via USB for new features and improvements.
Serial output at 115200 baud shows real-time states and transitions. Perfect for troubleshooting installation and verifying operation.
WiFi and Bluetooth capable ESP32 ready for future features. Firmware updates mean your converter gets better over time.
Hot rods, kit cars, scratch-built vehicles requiring signal separation. Professional-grade components handle high-power custom LED installations.
Corvette, Ferrari, Porsche owners doing taillight upgrades. Sequential LEDs and custom arrays need intelligent control and high current capacity.
Modernizing lighting while maintaining period appearance. Debouncing eliminates electrical noise issues common in vintage vehicles.
US to European spec lighting modifications. Professional components meet quality standards for high-end vehicle conversions.
Open firmware and serial debugging enable custom modifications. Hackable design appeals to technical enthusiasts.
Custom or commercial trailer applications. Robust construction handles vibration and environmental exposure.
