Adafruit GD25Q16 - 2MB SPI Flash in 8-Pin SOIC package

These little chips are like miniature SSD drives for your electronics. When you don't need something with as much storage as a micro SD card, but an EEPROM is too small, SPI (or QSPI) Flash chips provide megabytes of storage with minimal cost and complexity.

Commonly used on CircuitPython boards, they store code and assets such as animations, fonts, images, configurations, and audio clips. Perfect for adding datalogging storage as well. This particular chip offers 2 MByte of non-volatile storage (16 megabits) and is supported by CircuitPython and the Arduino SPI Flash library.

The standard SOIC size simplifies soldering, featuring the standard FLASH chip pinout, making it ideal for various applications including FPGAs or flash-less microcontrollers. For a creative enhancement, solder it onto the back of a QT Py board to augment flash capabilities, with the caveat of a bump on the bottom. Custom CircuitPython builds are required to interface correctly.

Compatible with boards like the Teensy 4.1, which accommodates an external FLASH chip on dedicated pads. Enhance your devices effortlessly with these versatile storage solutions.
