In the context of Industry 4.0, vocational education must prepare students for industries transformed by digital technologies. This study evaluates a microcontroller programming training kit aimed at enhancing practical competencies in line with Industry 4.0 requirements. Using a developmental-mixed method design guided by the ADDIE model and a sequential explanatory approach, the study involved needs analysis, design, development, implementation, and evaluation phases. The research was conducted at Bukidnon State University and involved 20 full-time lecturers from two state universities. Two survey instruments assessed the design, technical aspects, and usefulness of the training kit and instructional materials, using a five-point Likert scale to quantify responses.

The results indicate highly positive feedback across all evaluated aspects. The design received high ratings for feasibility, ergonomic layout, and clarity, supporting effective learning processes. Technical aspects such as reliability, ease of use, maintenance, and safety were also highly rated. The training kit was deemed an effective teaching aid, significantly enhancing student understanding and engagement. Qualitative feedback suggested design refinements, safety improvements, and innovative features such as the integration of the LoRa 32 OLED and additional cameras for monitoring student performance.
