Communication module adapter
This product is suitable for the following types of M.2 B KEY interface communication modules.
Note: Global Pass 5G/4G/3G/2G cellular functionality requires a communication module to function. If needed, please purchase SIM7600G-H-M.2, SIM8260G-M2, or SIM8262E-M2.
Supports M.2 NVMe SSDs
Compared to the Raspberry Pi's Micro SD interface, it offers faster read and write speeds, significantly improving system and file transfer efficiency, and also supports booting the Raspberry Pi from an NVMe SSD.
This image is for reference only. Please refer to the configuration list for detailed configuration.
Applicable to M.2 size
Applicable Interfaces
Note: Only NVMe hard drive protocol is supported.
More and richer interfaces
Equipped with multiple interfaces including ETH, MIPI, HDMI, Micro SD, USB, M.2 B-key, and M-key, making it more convenient to use.
Detailed hole design
Ensure that each interface fits perfectly against the motherboard.
The interface is clearly marked with silkscreen for easy viewing.
Heat dissipation design
The entire casing is made of aluminum alloy, which allows for large-area heat conduction and dissipation. Combined with heat dissipation fins, it provides more efficient heat dissipation.
Supports guide rail brackets
The back of the main unit has pre-drilled screw holes for mounting on a guide rail.
The image is for illustrative purposes only. This product does not include the guide rail bracket shown in the picture; it must be purchased separately.
