# Paul Sign ## Description Build your own Modular LED Sign! Operating Instructions: 1. [Important!] Power your buck converter and adjust the output voltage to 1.5V output before attempting to power the LEDs. If you want it to be simple and static intensity, first count how many LEDs you need to power and then determine your power requirements. E.g. R-24 T-14 F-15 M-33 Total: 86 ## Project Details - **Owner:** markwuflux - **Created:** 8/31/2023 - **Last Updated:** 8/31/2023 - **Visibility:** Public - **Copies:** 1 ## Key Components ### M1 — [lm2596 step down module with extra pads](https://www.flux.ai/markwuflux/lm2596-step-down-module-with-extra-pads.md) - Part Type: DC-DC Convertor - Datasheet URL: https://www.amazon.com/Valefod-Efficiency-Voltage-Regulator-Converter/dp/B076H3XHXP/ref=sr_1_8?crid=3IID127GL5R8S&keywords=step%2Bdown%2Bbuck%2Bconverter&qid=1693421258&sprefix=step%2Bdown%2Bbuck%2Bconverter%2Caps%2C139&sr=8-8&th=1 **Pins:** - GND OUT - GND VIN - OUT - VIN *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/markwuflux/paul-sign](https://www.flux.ai/markwuflux/paul-sign).* --- *Generated from [https://www.flux.ai/markwuflux/paul-sign](https://www.flux.ai/markwuflux/paul-sign)*
