T.F.SKYWINDINTL(TFSKYWINDINTL) | Professional Power Adapter for Dell Wyse 3040 SDI0 Mode Only TF-Compatible with Protective Cover and Chip Design

Suitable for Dell Dell Wyse3040 to TFNotes: 1. It is rumored that the PCIE channel of this machine is restricted and can only use SDI0 mode. (Currently sold as tin gold-sprayed fingers, the store tested it and it does not affect the use, so please be careful when photographing).2. Design: Since the SDI0 protocol does not support hot swapping, and the machine has a DC power supply, it is necessary to power off the device first, assemble the adapter board and insert the memory card. After installation, power on the machine.3. The store thoughtfully adds that the power supply protection uses a professional power chip, which has an ultra-fast microsecond level short-circuit protection function. It can effectively protect unsupported TF cards or damaged TF cards without damaging the memory card. The entire data line is of equal length, and the professionally designed snake-shaped routing lines are of equal length to ensure that the length of each data line is consistent.4. There is a socket called SDI0 NGFF E KEK. This socket can support conventional EMMC 4BIT design and use, and also supports the use of some TF cards using the SDIO protocol (some high-speed TF cards using the PCIE channel are not supported, but those using the SDI0 protocol with lower speed are supported)5. Known TFs using SDI0 protocol: 1.: Hiksemi SDXc U3 64G 2: KIOXIA EXCERIA G2128G blue card;It is recommended to use the lower-end U1 and U3 series. These series are known to support reading and writing speeds of 30-80M/S.Using the EMMC protocol, I expect that the speed is not ideal and is about the same as TF. The reason is that the bus does not add 8BIT data, and only half of the 4BIT is used. It can only be used for research and discussion. There are too many EMMc versions to explain.
