Yanhua ACDP BMW ISN Interface Board Set for MSD85

This set of interface boards allows a simpler method for ISN reading and writing of the MSD85 DME module. One of the boards connects directly to the DME to read it, and opening the DME allows the connection of the second board for writing purposes. This set enables reading the ISN and password of this module without opening the DME, as well as solderless ISN writing.
