Installation & Usage

  1. Clone the repository:
    sh
    git clone https://github.com/yourusername/your-pcb-repo.git
  2. Open the project in KiCad:
    • Open KiCad and load the required .pro file.
    • Access the schematic editor and PCB layout as needed.
  3. Generate Gerber files for manufacturing:
    • Use KiCad's "Plot" function to export Gerber files.

Bill of Materials (BOM)

Each project folder contains a BOM listing all components used in the design.

Questions

How big is the MicLed PCB?

It measures 44 × 0.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the MicLed use?

8 parts, built around the ATTINY85V-10PU. 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 MicLed KiCad files?

From the gokul-rm/PCB repository on GitHub, at the commit this page was made from: the board is ledMic/micLed.kicad_pcb and its schematic DLC/DLC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the MicLed design in my own project?

Its repository states no licence, so its author keeps all rights: ask gokul-rm before reusing the design.
