Hi. In the light of current events I think certification is relevant and primarily in the context of what kind of microcontrollers are there to ensure safety if the device itself is already certified. Please note what deep and informative thoughts can be seen in this thread.
Let me remind you that just recently I felt the need for visibility of certification by the community and @jans23 did not fail, they answered for their words. This is a great foundation for dialog with customers and future followers.
