Meet the RedBear Duo board: a tiny, Particle powered IoT board with Bluetooth and WiFi for smart home projects. It is HomeKit compatible, so you can control your smart projects with your phone and Siri. Thanks to the RBLink expansion board, additional sensors and modules can be added to the Duo without any soldering.
The Duo is developer friendly. You can use Arduino and Particle Web IDEs to write code for it. It is also JavaScript friendly. More information is available on Kickstarter.
