Purism Librem 5 is a privacy-focused open source Linux smartphone powered by NXP i.MX 8M processor that was launched via a crowdfunding campaign in August 2017 that ends up being extremely popular with over 1.5 million dollars raised.
At the time, the phone was scheduled to ship on January 2019, but a $299 development kit with board, display and accessories was slated to ship in June 2018. There have been some delays, but the good news is that Librem 5 development kits are now shipping so third party software development for the phone will now really get started.

The company has setup a Matrix channel for backers of Librem 5 developer kit to help them communicate with Purism engineering team and work with the community at large. If you don’t own the board, but are still interested in getting involved, you can ask to be added to the group by sending an email to [email protected] Work-in-progress documentation can also be found in the developer site.
