This Stock Main Board for Mavic 2 ZOOM/PRO is a disassembly board which is a 100% original DJI spare part that has been taken from another drone.It is 100% impossible to find factory fresh Main Boards for Mavic 2, so we have sourced a good stock of these disassembly boards which are LIKE factory fresh!It will always be our recommendation to buy an extra main board so that in the event that the drone has to be sent in for repair, it can be swapped back to the original stock board.DJI more than often just replace the whole aircraft with a brand new one which is very cool but in that case the downgraded stock board would be lost.
