+Reason for removal:
+- This board is sold only B2B, so that our community members from the
+DIY/hobbyist community and academia do not have access to the board. Our
+community members from the industry mostly develop their own hardware and,
+therefore, have no interest in supporting this board. As result, none of the
+RIOT core contributors has access to the hardware, preventing us from doing the
+necessary testing for maintaining this board.
