2022 Digi-Key Innovation Design Competition Participation Award List - A pile of memory cards [Copy link]

 

Although I didn’t win any prize in the 2022 Digi-Key Innovation Design Competition, I am very happy to have received a participation award in the end.

I originally planned to buy a development board to play with, but the several boards I looked at were relatively expensive and seriously exceeded my budget, so I gave up.

It just so happened that I needed a MicroSD card for the development I was doing, so I just bought all of them as memory cards.

After receiving the package, I realized that I had placed the wrong order because I hadn't paid attention to the information on one of the cards. I originally wanted a MicroSD card, but I chose an SD card. It would be very troublesome to exchange it, so I had to just go with it.

Thanks again to EEWorld and Digi-Key for hosting this event and providing the opportunity to participate.
I hope there will be more similar events in the future and more people will participate!!!

Digikey really sells everything

Haha, this is a good idea. SD cards can still be used in some older devices or development boards.

The author of the post is a person with big ideas. Now all the memory cards for electronic devices are available. Didn't he buy a few small-capacity ones? Many single-chip systems do not support large-capacity

Nowadays, the capacity of memory cards is getting bigger and bigger, and the price is getting cheaper and cheaper, but the quality is also getting worse and worse. Often, they can no longer be read after a while of use.

If you buy a SanDisk card reader + a SanDisk TF card, the situation you described will not occur.

I have bought a lot of small capacity ones before.

Grocery stores are much more expensive than Taobao

It is quite useful on the microcontroller development board, hahaha

This depends on the flash technology used. If you want a stable and reliable one, you should choose an industrial-grade SLC card, which will not break no matter how hard you try, but it is very expensive. Currently, there are dozens of GB cards on the market for just over ten yuan, and it is considered good if the full disk can be erased and written 1,000 times.
