Educational Firmware Over-the-Air (FOTA) Kit for Automotive Systems in STEM Education

Abstract

The growing complexity of automotive electronics and the increasing demand for hands-on STEM education highlight the need for practical tools that introduce students to cutting-edge technologies. Firmware Over-the-Air (FOTA) technology, widely used in the automotive industry for remote software updates, remains underutilized in educational contexts. To bridge this gap, we present the Educational Firmware Over-the-Air (FOTA) Kit, a comprehensive learning platform designed to teach foundational and advanced concepts in embedded systems, secure communication, and automotive technologies. The kit integrates hardware components such as Raspberry Pi, STM32 microcontrollers, and Controller Area Network (CAN) Bus interfaces with software modules covering bootloaders, encryption protocols, and an intuitive Graphical User Interface (GUI). These elements simplify complex automotive technologies for classroom use. Through interactive activities, including writing custom bootloaders, configuring CAN networks, and implementing AES encryption, students gain practical, real-world experience while developing technical proficiency. Initial deployment of the Educational FOTA Kit has demonstrated its effectiveness in enhancing student engagement, bridging theoretical knowledge and practical application. Quantitative results indicate improvements in problem-solving skills and a deeper understanding of secure firmware updates. By fostering innovation and technical expertise, this kit prepares students for emerging fields such as IoT, automotive engineering, and cybersecurity. The Educational FOTA Kit marks a significant advancement in STEM education, offering a dynamic and versatile platform aligned with the technological demands of modern industries.
