Adafruit W25Q80BV - 1 MByte SPI Flash

This adorable little DIP chip offers a megabyte of flash storage, providing a solid-state, cost-effective alternative to an SD card, with significantly more space than your microcontroller's EEPROM.

Ideal for storing or retrieving up to 1 Megabyte of data, it seamlessly integrates with any microcontroller via SPI. Ensure to power it with 3.3VDC and employ a level shifter if utilizing a 5V microcontroller, such as an Arduino. A 74LVC245 or a 4-transistor level shifter works perfectly.

Additional resources include a detailed datasheet and a minimalistic SPI Flash library for Arduinos available on GitHub. The ease of integration makes it a practical choice for expanding your project's data storage capabilities.
