About this Report
This report explores how developers begin their IIoT journey: which development boards they start with, how they experience onboarding across tasks and ecosystems, and how these patterns differ by experience level, role, and region. The findings highlight where the industry is lowering technical barriers and where better documentation, community support, or learning pathways are still needed. Insights come from the 30th edition of the Developer Nation survey, which ran from June to August 2025 and reached 830 developers worldwide involved in IIoT projects.
Key Questions Answered
Arduino is one of the most common starting points in IIoT, significantly ahead of other development boards, except for legacy microcontroller kits.
One in eight developers cannot recall their first IIoT board, suggesting that IIoT entry is often informal and opportunistic.
Newer entrants to IIoT and today’s students largely report starting with Arduino as their first development board.
