🚀 Overview
The Battery Level Indicator is an open-source project designed to visually display the charge level of a battery using five green LEDs and a sixth red LED for critical low levels. The board also features an ON/OFF button that activates the system, illuminating two white LEDs when turned on and two blue LEDs at other times.
🎯 Purpose
- 🔋 Battery Monitoring: Provides an intuitive LED-based display of battery charge levels.
- 🔘 Power Control: Includes an ON/OFF switch for system activation.
- 🌟 User-Friendly: Simple and effective visual indicators for battery status.
- 🛠️ Open-source & Customizable: Modify and adapt for various battery-powered projects.

Questions
How big is the BatteryLevelIndicator PCB?
It measures 60.3 × 9.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BatteryLevelIndicator use?
14 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the BatteryLevelIndicator KiCad files?
From the mpek29/BatteryLevelIndicator repository on GitHub, at the commit this page was made from: the board is design/BatteryLevelIndicator/BatteryLevelIndicator.kicad_pcb and its schematic design/BatteryLevelIndicator/BatteryLevelIndicator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BatteryLevelIndicator design in my own project?
Its repository states no licence, so its author keeps all rights: ask mpek29 before reusing the design.
