• Printed circuit boards (PCBs) are essential for developing Internet of Things (IoT) devices. The proper design of these boards is vital to ensure that they comply with industrial standards. Despite the high demand for qualified professionals to develop this kind of PCBs, there is still a considerable gap between the skills taught to students during their academic journeys and the industry’s needs. In general, many skills in design rules and technical aspects necessary to assure the proper development and performance of such devices are acquired by engineers based on experience in practical projects. Having this in mind, this paper presents a learning module that focuses on practical aspects and concerns regarding the design rules of PCBs. In this module, students follow a hands-on activity to design an IoT-based device PCB, employing a microcontroller to read one accelerometer data and communicate via Bluetooth. During the project development, the instructors discuss and share practical experience in various electrical aspects of the PCB components layout that can affect the circuit’s performance. The attendees’ positive feedback and performance during the practical activities demonstrate the effectiveness of the learning module.
