Nordic Developer Zone - The Nordic developer’s best friendThe original goal of Nordic Developer zone was to create a resource for our customers that would complement direct Nordic technical support. It should simplify and help them with their design efforts. It should be a place where everyone can contribute, Nordicers and our customers and partners alike. It had a simple mantra – ‘Ask questions, share info, and be inspired’. As Nordic Developer Zone enters its 4th year, we can safely say i...
