4.3 Practical Activity: Routing a PCB

Practical Activity: Routing PCB Tracks

Objective: Learn how to connect electronic components on a PCB layout using copper tracks in EasyEDA or KiCad.

Instructions:

  1. Open your existing PCB layout project in EasyEDA or KiCad.
  2. Check that all components are placed correctly.
  3. Identify the unrouted connections between component pads.
  4. Select the routing tool.
  5. Draw copper tracks to connect the required pads.
  6. Check track widths, clearances, and connections.
  7. Run the Design Rule Check (DRC), correct any errors, and save your project.

Expected Result:

A PCB layout with correctly routed copper tracks, no unintended unconnected nets, and fewer or no design-rule violations.

My name is Eric Nduwayezu, an Electrical and Electronic Engineer, inventor, entrepreneur, and technology developer. I am the Founder and CEO of GATO GROUP LTD, where I focus on developing practical technology solutions that address real-world challenges in communities.
My background is in Electrical and Electronic Engineering, with experience in IoT, PCB disgn , software simulations, embedded systems, automation, electronics, sensor systems, and intelligent monitoring technologies. I enjoy transforming ideas into functional prototypes by combining hardware, software, communication technologies, and automation.
One of my key projects is Power Easy, an assistive smart-energy solution designed to make prepaid electricity management easier, particularly for people who may have difficulty physically accessing elevated electricity meters. The project was inspired by a real experience in my family and reflects my approach of developing technology around genuine human needs.
I have also worked on projects involving smart electrical monitoring, environmental and water-quality monitoring, fire and gas detection, smart doorbells, traffic management, biometric access control, LoRa communication, and automated electrical systems. These projects have strengthened my practical skills in micro-controllers such as ESP32 and Arduino, sensors, wireless communication, embedded programming, and system integration.
As an entrepreneur and innovator, I believe technology should not only demonstrate technical capability but should also solve meaningful problems and create practical value. I am particularly interested in developing affordable and scalable solutions that can be adapted to local needs.
I also enjoy sharing technical knowledge and helping others learn through practical projects. My teaching philosophy is based on learning by doing: understanding the problem, designing a solution, building a prototype, testing it, identifying failures, and continuously improving the system.
My long-term goal is to continue developing innovative engineering solutions, build sustainable technology businesses, and contribute to the growth of a stronger culture of engineering, innovation, and entrepreneurship.
