eMMC (Embedded Multi Media Card) embedded multimedia card is short, having a data transmission speed, stable, consistent interface definition, etc., for a large number of new smart phones, computers, and other intelligent devices. There are at EMMC interface protocols in a very special setting, it can be backward compatible with SD card interface protocol, which laid the foundation for EMMC magic change U disk. With the arrival of 5G mobile phones, mobile phone replacement will be faster and faster, and now the family who has not been eliminated a few old phone, it really does not bring back enchant a bowl? [Laughs cry]
old phone, they're worth a lot of bad cell phone for professionals, mobile phone parts usefulness of a particular person is still quite large, in fact, for us average consumer, old phone, the phone is also bad value, but also smart old machine, we can turn them into monitoring into set-top boxes, and so on; as bad phone, we can split out the inside of the flash memory to transform into a U-disk, use a lot. Today, Hong Wang Semiconductor offers several eMMC re-use ideas, you can choose whichever is more suitable, Friendly reminder, the rectification method is not suitable for pure white, so be careful.
A thought: EMMC + SD Card Reader
After EMMC defined for the pin and TF / SD card reader, they are connected to the corresponding pins, without opening the card. Advantages EMMC + SD card reader U disk transformation is to save money, save thing, can retrieve the data, read and write speed disadvantage is very dregs.
Two ideas: EMMC + U disk control board
EMMC MPU online very cheap, only 10 yuan plus a shell, we can choose to Yasukuni and NS1081, they support BGA162,221,153,169. Use Yasukuni control board does not need to open the card, but the transformation of U disk is slow, and the EMMC + SD card reader similar; select NS1081, need good hand-welding technology, but also open card (open card software in the amount of U disk network capacity can be downloaded), the transformation of U disk, speed is relatively faster, but heat large.
Thinking three: EMMC Reader
EMMC reader can read and write, format, test EMMC. The disadvantage is that expensive, a reader can only accommodate one kind EMMC EMMC.
Four ideas: eMMC change U disk
This method is suitable interested in hardware DIY friends, hands-on ability, not the pursuit of more cost-effective and practical, more of a sense of accomplishment and joy. If you happen to have around eMMC bad old phone or mobile phone, and you have the time, energy, interest, you can try eMMC transformation U disk. If you just need a removable disk, it is better to just buy the U disk or SSD buy add the adapter box, U disk transformation cost is not low, and eMMC transformation U disk speed is not OK. All in all, with eMMC transformation U disk, the disk is not suitable for a player we need U.
Today, Hong Wang Semiconductor offers several ideas for everyone eMMC re-use, and if there are articles of interest method, can Comments, Hong Wang semiconductor late will bring you a detailed tutorial, please stay tuned to us.
