LED-Streifen mit hunderten von Leuchtdioden: YULC – der neue Controller für excessive Stromversorgung
In the world of LED strips, excessive current is a common problem. To power these strips, a new controller called YULC has been developed. YULC stands for “Yes, a USB Type-C LED Controller” and it can supply up to 20 A directly from a USB-C port. This is no small feat, considering that even a five-meter long strip with 60 LEDs per meter can consume up to 18 A of current.
Traditionally, LED strips have been powered by external power supplies, which increased the cabling effort. The YULC controller changes this by providing direct power supply from the USB-C port. This means that the LED strip and the controller are connected via screw terminals, and the Leuchtdioden can be controlled directly from the board.
To ensure that the LED strip is protected from short circuits, the YULC controller is equipped with KFZ-Sicherungen (20 A) to prevent damage to the board. Two safety holders are provided for this purpose, depending on whether the power supply is via USB or a hole.
The ESP32-S3 processor sits at the bottom of the board and is responsible for controlling the LEDs. The processor is supplied with a 5 V voltage regulator, which also powers the LEDs if they are operated at higher voltages than 5 V. The board has 15 GPIO pins, six of which are used for internal purposes.
The YULC controller is currently available as a crowdfunding project on AAElectronics and will soon be available for purchase. For more information, including the schematic diagram, please visit the GitHub page.
This new controller offers a convenient and efficient solution for powering LED strips with hundreds of Leuchtdioden. With its direct power supply from the USB-C port, the YULC controller eliminates the need for external power supplies and reduces the cabling effort. Whether you’re looking to create a stunning light installation or simply add some colorful accents to your home decor, the YULC controller is definitely worth considering.
