KiCad PCB design for a single-cell lithium-ion battery charger with 5 V USB-C input and a 10-LED charge level indicator. The board uses a Texas Instruments BQ24092 linear charger IC and an LM3914 dot/bar display driver for charge indication, with a JST connector for the battery pack.
The project includes the full KiCad schematic, PCB layout, and Manufacturing Gerber / drill files. Component reference datasheets for the BQ24092 and LM3914 are included alongside 3D models for parts not covered by standard libraries.
