I have just come into contact with file system filtering. I watched Chu Kuangren's tutorial and gained a lot. Because it only supports FAT file system, I modified it slightly to support NTFS (because ...
I recently made a boost and current expansion circuit using 34063 (as shown below). The input is 5V/500mA, and I hope to output 9V. The output current should be as large as possible. Please give me so...
I wanted to use 2410 in a product, so I bought it to use as a development board. But after I bought the development board, I never made the product.
So the development board has been left there, with ...
