Overview

This project provides a dedicated PCB for the Hi-Fi microphone circuit originally demonstrated by DIY Perks. While the original build used a stripboard, this KiCad project offers a custom-designed PCB, making the assembly process more straightforward and the final product more durable and professional.

Features

• Dedicated PCB Design: Eliminates complex wiring on stripboard, improving reliability.
• Compact & Clean Layout: Components are organized for a tidy and space-efficient build.
• Easy Assembly: Through-hole components and clear labeling simplify the soldering process.
• Professional Finish: Achieve a high-quality result comparable to commercial products.

PCB Design

The project was designed in KiCad and consists of a single two-layer board.

Getting Started

Hardware Assembly

1. Manufacture the PCB: Use the KiCad project files to export Gerbers and order the board from a PCB fabrication service.
2. Gather Components: Refer to the schematic for the complete Bill of Materials (BOM).
3. Solder Components: Assemble the board, starting with the lowest-profile components first.
4. Testing: Follow the testing and calibration steps shown in the original DIY Perks video.

Opening the Project

1. Install KiCad 7.0 or later.
2. Open the mic_base.kicad_pro file to access the schematic and PCB layout.
