# Lethal Company Pro Flashlight Power Board V1 ## Description Lethal Company Pro Flashlight Broken Features: - U2M cannot be line powered from this circuit so the LED driver does not regulate. [Find the acompanying button board here](https://www.flux.ai/markwuflux/lethal-company-pro-flashlight-button-board) -Ultra bright -Makes click noise from speaker -Wirelessly transmits battery life (maybe use Ubo to receive this) -Drive a SST-40 Chinese LED I want this thing to be super bright! The brighter the better, but keep it simple. These LEDs will draw a lot of power, so we need some sort of CC source. It doesn't have to have high bandwidth. I am thinking about a DIY microcontroller buck converter with PID duty cycle control. Mistakes in this V1 design: - No pullup resistor on PG of Module1 ## Project Details - **Owner:** markwuflux - **Created:** 2/2/2024 - **Last Updated:** 3/31/2024 - **Visibility:** Public - **License:** https://creativecommons.org/licenses/by/4.0/ - **GitHub Link:** https://github.com/markwu2001/lethal-company-flashlight - **Stars:** 1 - **Copies:** 2 ## Key Components ### BT1 — [BH-18650-B1BA002](https://www.flux.ai/markwuflux/bh-18650-b1ba002~i9.md) - Manufacturer Name: ASE Technology Holding Co.
