After revealing that the first modular phone might cost as little as $50, Google announced the first Project Ara Developer Conference, which is to be held on April 15th and 16th this year. This one is going to be the first of three Project Ara related conferences that are going to be held this year, concentrating mainly on the Ara Module Developers' Kit (MDK). Expect the kit to be released around the time of the conference, i.e. in April.
For details, as well as a full schedule will be released in the coming weeks. People who cannot attend the conference physically, don't worry. The entire event will be broadcasted live.
