🛠️ Getting Started

  1. Install KiCad (v7 or later recommended).
  2. Clone this repository:
    bash
    git clone https://github.com/ANSHAD134/PCB-Files.git
  3. Open any project's .kicad_pro file in KiCad to view/edit the schematic and PCB layout.
  4. Gerber files (inside Graber/ folders) can be sent directly to a PCB fab (JLCPCB, PCBWay, etc.) for manufacturing.

Questions

How big is the Amplifier PCB?

It measures 55.7 × 48.7 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Amplifier use?

20 parts, built around the TIP41 and TIP42. 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 Amplifier KiCad files?

From the ANSHAD134/PCB-Files repository on GitHub, at the commit this page was made from: the board is amplifier/amplifier.kicad_pcb and its schematic NE555 LED Flasher – KiCad PCB Design/NE555 LED Flasher – KiCad PCB Design.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Amplifier design in my own project?

Its repository states no licence, so its author keeps all rights: ask ANSHAD134 before reusing the design.
