SiPy 22dBm

The SiPy comes in two development board versions: the 14dBm version for Europe and the 22dBm version for pretty much the rest of the world.

The SiPy includes 2 years of Sigfox connectivity as well as full access to the new Sigfox geolocation service.

Compatible with Pycom's Pysense and Pytrack sensor shields.

OEM modules are also available.
