Description
Choose the right brightness for your LEDs. LED RESISTANCE HELPER Tool
This board features 6 different resistance values so you can find the right brightness for your project.
- Connect only one jumper at a time.
BOM, GRBRs, Schematics, Layouts, Centroid files are all included.
Long Description:
- This project is a resistor testing board designed to help you quickly determine the right resistance value for adjusting LED brightness or other current-limiting applications.
- The board includes 6 different resistor values, each selectable with a simple jumper. By connecting one jumper at a time, you can instantly compare brightness levels and choose the resistor that best fits your project.
Features:
- 6 resistor values for easy testing.
- Simple jumper selection — connect only one at a time.
- Compact PCB design for convenient use on the bench.
- Ideal for choosing resistor values for LEDs.
Great learning tool for beginners experimenting with Ohm’s law and current limiting.
Included Files:
- BOM (Bill of Materials)
- Gerber files
- Schematics
- PCB Layouts
- Centroid files
Why do I use it?
Instead of trial and error with loose resistors, this board provides a ready-to-use solution for quickly finding the right brightness level.
Applications:
- LED brightness testing
- Quick current-limiting experiments
