Traditional breadboards have long served as a cornerstone in electrical engineering education, offering students a hands-on introduction to circuit design. However, their inherent challenges - such as wiring errors, instability, and difficulties in managing complex circuits - limit their effectiveness in modern educational settings and highlight the need for a more robust and future-ready alternative. MEXLE 2020 addresses these challenges, providing a modular, multimodal experiment and learning environment designed for practical and scalable experimentation.

MEXLE 2020 replaces breadboards with compact, pre-configured modules that integrate passive and active components, reducing setup complexity and enhancing experimental clarity. This modular framework simplifies circuit construction and analysis, enabling students to focus on fundamental principles without the distractions of intricate wiring. By fostering a structured yet flexible approach to experimentation, the system strengthens the connection between theoretical concepts and practical applications, enhancing both understanding and engagement.

Beyond electrical engineering labs, MEXLE 2020 modules are also prepared for microcontroller courses, where they serve as versatile hardware building blocks for embedded systems projects. By allowing students to quickly assemble circuits and focus on programming microcontroller-driven functionality, By enabling students to quickly assemble circuits and focus on programming microcontroller-driven functionality, the system minimizes the need for custom circuit development while broadening the range of achievable projects.

This paper outlines the development of MEXLE 2020, its planned integration into the second-semester electrical engineering laboratory at Heilbronn University, and its potential expansion into other disciplines. We discuss the expected benefits of the modular approach, including improved learning efficiency, reduced troubleshooting time, and increased consistency in experimental setups. Our goal is to enhance the accessibility, consistency, and pedagogical value of practical experiments, ultimately providing a scalable and modern alternative to traditional methods.

Looking forward, the MEXLE 2020 system offers the potential to evolve into a Lab-in-a-Box concept, enabling students to combine modular experimentation in the lab with preparatory and supplementary activities at home. Designed for adaptability, the system is well-suited for foundational electrical engineering courses and offers significant potential for broader applications, including electronics and control theory laboratories.
