I currently am using the DJI RC (screen) controller with my Mini 3 Pro. I'm thinking of purchasing the DJI RC-N1 (no screen) and am also seeing used DJI RC231 controllers for sale. I'm having a hard time finding reliable info (multiple sources) on whether the RC231 is the basically the same inside (same occusync/range etc.) and just different labeling on the speed modes. Tripod vs Cine switch labeling on the front. I think the RC231 didn't originally work with the M3Pro but now does and would appreciate confirmation from any users. Thanks, Bill
