H2S-Dev board is a ready-to-use, Open source hardware, Arduino compatible, LoRaWAN Helium network sensor development board. It is capable of implementing a number of sensor (Basic and Full variant) and positioning applications (Full variant only). The board is mainly targeted to makers and hobbyists.

I started providing LoRaWAN coverage in my city by mounting the ThinkNode G1 gateway to my attic and I made a portable device to test out the reach that it has.
