# On Air Modular V1 ## Description Build your own Modular LED Sign! This design prioritizes accessibility which means that the BoM can be ordered on Amazon and that everything was designed with solder-ability in mind. NOTE: This board is still an unfinished prototype that has not been built and verified. 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 cannot power the buck converter, just turn the potentiometer counterclockwise to its maximum setting. ## Project Details - **Owner:** markwuflux - **Created:** 8/30/2023 - **Last Updated:** 10/24/2023 - **Visibility:** Public - **Stars:** 4 - **Forks:** 5 - **Copies:** 5 ## Key Components ### B1 — [BK-18650-PC2](https://www.flux.ai/vasyl/bk-18650-pc2~kg2.md) - Voltage: 4.2V - Manufacturer Name: MPD (Memory Protection Devices) - Datasheet URL: https://www.memoryprotectiondevices.com/datasheets/BK-18650-PC2-datasheet.pdf - Manufacturer Part Number: BK-18650-PC2 **Pins:** - NEGATIVE [pin -] - POSITIVE [pin +] ### M1 — [lm2596 step down module with extra pads](https://www.flux.ai/markwuflux/lm2596-step-down-module-with-extra-pads~1x.md) - 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 - Part Type: DC-DC Convertor **Pins:** - GND OUT - GND VIN - OUT - VIN ### SW1 — [TK-6580-1](https://www.flux.ai/vasyl/tk-6580-1~a3n.md) - Manufacturer Name: Yuandi - Manufacturer Part Number: TK-6580-1 - Part Type: Switch - Datasheet URL: https://datasheet.lcsc.com/lcsc/2008311534_Yuandi-TK-6580-1_C528778.pdf **Pins:** - 1 [pin 1] - 2 [pin 2] - 3 [pin 3] - 4 [pin 4] - 5 [pin 5] - 6 [pin 6] *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/markwuflux/on-air-modular-v1~qu](https://www.flux.ai/markwuflux/on-air-modular-v1~qu).* --- *Generated from [https://www.flux.ai/markwuflux/on-air-modular-v1~qu](https://www.flux.ai/markwuflux/on-air-modular-v1~qu)*
