Applicable to for 5, support IEEE 802.3af/at network standards. Support NVMe protocol M.2 interface hard disk, high-speed reading and writing. GEN3 theoretical transmission speed 8Gbps, measured reading and writing speed is about 800MB/s. Applicable to for 5, can be connected to Pi 5 through 16PIN cable, based on 40PIN GPIO interface design, top lead pin, convenient access to other expansion boards. Onboard dual LED indicator. Working status indicator light, flashes when the hard disk reads and writes data; power indicator light, always on when powered on; the working status of the device is clear at a glance. Supports NVMe hard disk protocol, compatible with 2230/2242 size M.2 hard disks, supports Gen2 and Gen3 modes, and supports booting Pi 5 from SSD. Supports PoE Ethernet power supply, only one network cable is needed to connect to the PoE device to enable for the to connect to and power it. (Network cable not included) Note: for and hard disk are not included. PoE power input: 37V ~57V DC input Power output: GPIO pin header: 5V 5A (MAX) Network standard: Support IEEE 802.3af/at PoE (Different batches may have different printings, which not affect the use) Color: Blue Material: PCB Package Contents: 1 * expansion board 1 set * accessories (accessory colors are random, specified colors are not accepted) Only the above package content, other products are not included.
