The LoPy Kickstarter campaign will launch tomorrow. Basically this board can be configured as a Node or as a "nano" Gateway supporting up to 100 Nodes itself. Runs micro-python, combines LoRa with Wifi and Bluetooth in the one package and is from the same stable that created the WiPy. Its incredibly cheap at only €48 with an antenna.
You can preview the campaign here (I am not affiliated):
