A Nintendo Switch 2 MicroSD Express to M.2 open-source adapter is in the works, potentially allowing users to get more storage space at a lower price.
The project's GitHub, which was launched this week, provided the first information on the process, revealing that such an adapter is made possible because the console's MicroSD Express slot supports the SD Express 7.1 standard, which exposes a true PCIe Gen3 x1 interface and utilizes the NVMe protocol for communication. As such, the adapter maps PCIe x1 from the Switch 2’s MicroSD Express slot to a standard M.2 2230 NVMe SSD, and no protocol translation is required as the Nintendo Switch 2 host controller handles everything.
Currently, the project's development seems to be proceeding smoothly, and the team is actively developing the PCB layout and testing. While the adapter, on paper, should be working without any issue, the team warns that there's the possibility of power-related issues related to the power draw of the M.2 SSD, which could be more than the Nintendo Switch 2 could handle, so a basic level of power filter has been added to hopefully establish a connection. Still, it is advised only to use low-voltage M.2 2230 NVMe drives and not attempt to use the adapter on legacy MicroSD slots, such as those of the original Nintendo Switch systems.
While the Nintendo Switch 2 will not be remembered as an innovative gaming system, it is an excellent console and a clear upgrade from its predecessor. You can learn more about the new generation system from Nintendo in Chris's review.
