The 900MHz Explorer Block has been a huge success. We have been amazed by the things people have done with it and demand keeps increasing. Because of this, Enhanced Radio Devices will continue to keep the 900MHz Explorer Block in stock for the foreseeable future. We are trying to match demand with production runs, so if you see Explorer Block go on back order, it means we are still waiting on a production run.
Getting the 900MHz Explorer Block going can be a bit complicated for some, so we have decided to start stocking a version of the Intel Edison with Jubilinux pre-installed. This will make it a lot easier for our customers to get started quickly. These have also sold out very fast, so we are working to increase inventory.
If there is anything else you can think of to help you get started quick with Explorer Block, don't hesitate to ask.
