RAKwireless Blues.ONE is a LoRaWAN IoT development kit that also supports LTE-M and NB-IoT cellular connectivity through the Blues NoteCard which comes with 10 years and an upgradeable 500MB cellular data plan.
The devkit relies on the WisBlock modular IoT prototyping system with the RAK13102 WisBlock Blues Notecarrier, the Blues NoteCard, a WisBlock Base Board, and a WisBlock Core module. It can be used to prototype or develop IoT devices for industrial automation and asset-tracking applications.

Everything comes as a kit which will allow you to connect compatible sensors or modules, switch the Core module, and so on. The basic kit only comes with the electronics, antennas, and a cable, but RAKwireless also offers an optional waterproof Unify enclosure and/or a battery.
The Blues.ONE kit is basically another version of the Link.ONE kit introduced last year (see review for details) that ships with Blues Notecard instead of a Monogoto SIM card. The new IoT development kit is also programmable with the Arduino IDE, and a GPS tracker firmware with source code can be found on GitHub. Detailed documentation does not seem to be up at that stage.
The Blues.ONE IoT kit can be pre-ordered on the RAKwireless store for $106 and up. with shipment scheduled to start in about 15 days
