Works With 2024
Where Innovation Meets Implementation
Works With, the premier Silicon Labs developer event of the year, is back! This year will feature three regional, in-person developer events in San Jose, Hyderabad and Shanghai. Participants will experience a full day of training sessions and dedicated technology tracks, as well as a demo lab and networking opportunities. The agenda for these in-person events will also include engineer-led, hands-on workshops where participants will learn practical ways to accelerate the development of their projects with the latest tools, techniques, and resources.
