How hard can this be? I just need to figure out what the USB controller is and what chip I can use to replicate the functionality. Looks like a USB controller on the back under the blob and the top is just a card slot and a bunch of SMD componenets. I though this would be a simple little weekend project.Ĭheck this out. A RAM chip, a USB controller and maybe a crystal and a couple of SMD caps/resistors. Why is this such a secret? Why is it so difficult to make something that you can buy at the checkout of a quickiemart for $5 bucks? Ever crack open a thumb drive? There’s nothing to them. Once I Googled for a schematic, I realized that it’s not a matter of just chalking up a PCB and having it fabbed. I was just sitting around thinking of cool stuff to make and I though it would be pretty neat to make my own USB Mass Storage Device.
I have plenty card readers and thumb drives already. I’m not looking to make a $5 USB card reader. Using Arduino is not meant to be an alternative to or saving money on consumer electronics, it is to create things or even products NOT sold as consumer electronics, which is how and why arduino became popular.
#USB CARD READER FOR PC FULL#
Your intellect alone is not able to beat capitals they own. Quickly access or back up photos and video from your CFast 2.0 memory cards to your tablet, laptop, or computer - CFast Card Reader - USB 3.0 - USB Powered CFast reader for CFast 2.0 / 1.0 cards - Save time downloading high-resolution photos and full HD videos from your DSLR camera or camcorder to your computer with USB 3.0 (5Gbps) - Portable CFast Reader - Backward compatible w/ USB 2.0, 1.x. If you can make such drive yourself for $5, that company would be able to do it at $0.50 and still make money. You forgot that the no-name company has a million dollars invested in manufacturing equipment and space and some dozens of qualified workers and circuit RD professionals and contracts to purchase bulk parts at cost you can't believe etc. Sure, you can go out and spend $5-$10 bucks on a USB card reader.but wouldn't it be cool to make your own mini "solid state drive"?
So how is it a no-name company in China can make a $5 USB stick no larger than the USB connector itself? How are they pulling it off? Why is it you can't make a DIY thumb drive? There has to be a way, not because it's better than a SanDisk or a Cruiser, etc.but because we can!!
