No problems with the “onboard” hardware (GPS, Compass, Baro) but instead I am annoyed with the SDP33 airspeed sensor connected to the Matek:
Does compass or barometer work for you ? If not, this would also be an indication of a defective cable. The cable has different connectors, at the FC the order is 5V-GND-CAN high-CAN low. The Clickmate connector is correctly standardized with 5V - CAN-h - CAN-l - GND.
