For the Remote Id for the Trinity F90 I need to know the Serial Number of you payload or get a photo of your PMB on the payload.
You need to access to your payload compartment to see if only the Remote ID kit is needed or if a ready bay compartment is needed instead, open up the payload compartment cover (exposing access to the PMB board) and look for the following connector (circled in red in the photo below) on the PMB board. If the connector (not the cable with black wires, but the actual connector) is present on the board, only the Remote ID kit is needed, but if the connector is missing from the board, a ready bay compartment is needed.
I can then quote this for you.
On the F90+ each payload requires a Remote ID module.
