Hello @Pauleera , yes the board can still be used, the documentation is available here: https://docs.pycom.io/
The Pybytes platform however is no longer online, and old Pycom products are not supported on the SG Wireless Cloud platform.
Sorry, the board does not support Sigfox at this time. We used the old Pycom documentation as a base and it seems there are instances where the team did not remove Sigfox properly. We will review and remove all mentions to Sigfox. We may support Sigfox again in the future but no decision has been made at this point.
