Jul 19, 2019 · I need memory to read from, for my project. I first intended to use an SD card, but I now found out a W25Q64/128 SPI Flash is more practical, since I don't need to write data. However, this W25QXX Flash works with 3.3V SPI and the Arduino Mega has a 5V SPI. By searching around, I find many solutions, but two that work which are quite different:

Mar 10, 2017 · SPI flashes usually have a very large erase unit (e.g W25Q64 is 4 Kbytes size). That's the minimum size that FatFs can operate on the SPI flash. So how do I solve this problem? Or are there other flashes that can be erased in a smaller unit?
