Project Schematic
andrasime23-create/Personal-projectsA short look at the projects where I put my dedication to the test. By bridging the gap between PCB design and software development, I’ve spent years turning 'what if' into 'it works.' I believe that true technical expertise isn't studied—it’s built, debugged, and refined through relentless practice.

Augmented Reality Light Engine PCB Design/README.mdAugmented Reality Light Engine
This project involves the complete design and development of an Augmented Reality (AR) Light Engine module. It showcases expertise in high-density electronics, bridging hardware architecture with advanced PCB manufacturing techniques.
Core Architecture of the project implemented in KiCad:
-Powered by a DPLC2020 ASIC (ARM Cortex M3) and a DLPA2020 PMIC to manage complex power rails.
-Optical Engine: Integrates a DLP2020 MEMS projector with OSRAM RGB LEDs to generate high-fidelity AR visuals.
-Rigid-Flex Technology: Designed on a 6-layer Rigid-Flex PCB to fit the ergonomic constraints of wearable smart glasses.
-Signal & Power Integrity: Implementation of 50Ω single-ended and 100Ω differential pairs for high-speed video data, alongside optimized switching loops for EMC compliance.

Questions
How big is the Project Schematic PCB?
It measures 84.5 × 50 mm and has 6 copper layers, 1.59 mm thick.
What parts does the Project Schematic use?
104 parts, built around the PMEG4002EL. 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 Project Schematic KiCad files?
From the andrasime23-create/Personal-projects repository on GitHub, at the commit this page was made from: the board is Augmented Reality Light Engine PCB Design/Project_Schematic.kicad_pcb and its schematic Augmented Reality Light Engine PCB Design/Project_Schematic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Project Schematic design in my own project?
Its repository states no licence, so its author keeps all rights: ask andrasime23-create before reusing the design.
