UHS-I Extender cable Test:

The dotted line is the speed measurement of UHS-I high-speed card, the theoretical value is 104MB/s, and the measured speed is about 95MB/s
The solid line is the speed of SD ordinary card, the theoretical value is 25MB/s, and the measured speed is about 21MB/s

Is there any EMI shielding for Cable?

No metal shield. The extender utilizes the latest materials for EMI shielding with five sole flat cables design. This technique allows each cable to be fully covered by electromagnetic interference shielding with conducting polymer to guard against incoming or outgoing emissions of electromagnetic frequencies, minimize disturbance and degradation on performance, and reduce the weight of the extender.

Can wires and PCB connectors be split?

No, in order to purify the signal transmission and avoid the accident of wire falling off, our wire and PCB connectors is soldering and protected by the heat shrinkable tube sleeve, so the product can not be separated.

Cable thickness? Can it be bent?

The thickness of the wire is 1.05mm, and it can be bent and folded without affecting the use.

How compatible is the SD extension cord?

The compatibility of the SD extension cable is related to the cable length. The cable length is less than 30cm and supports UHS-I 104MB/Sec full speed. The cable length is more than 30cm and only supports ordinary SD cards without the "I" character. The SD cards will have a speed mark. As shown below

Does it support hot swap?

Hot plugging is not supported. You need to shut down the device before installing the SD extension cable.

Does it support UHS-II, III SD cards?
It can be used, but it can only play the performance of UHS-I, not full speed
