Hello I have experience in programming embedded systems including arduino About your request, I don't know if the CID of the SD cards is writable. That value is given in manufacturing and is read only. However, I can help you creating a HW and SW design for a SD communication. I would like to know the purpose of CID change and maybe we can find a walkaround for achieve your goal without CID Regards
