{"title":"SPI Flash Breakout - W25Q16 16Mbit / 2MB","handle":"adafruit-spi-flash-breakout-w25q16-16-mbit-2-mbyte","url":"/products/adafruit-spi-flash-breakout-w25q16-16-mbit-2-mbyte","description":"When an SD card is overkill, this small board gives your microcontroller project a handy chunk of non-volatile storage for files, images, fonts, audio clips and other data. It uses a W25Q16 flash chip, providing 16 Mbit / 2 MByte of external memory with lower cost and power usage than a full SD card setup.This breakout is wired for single-channel SPI only, rather than QSPI, and it includes on-board level shifting so it can be used safely with 3V or 5V power and logic. Adafruit has also added a 3.3V regulator and a pull-up on CS, making it straightforward to connect to a wide range of development boards and older 5V-compatible designs.The flash chip comes blank and does not include a wear-levelling subsystem, so you can access it as a flat memory space or format it with a filesystem such as littleFS or FAT if that suits your application. For Arduino users, the Adafruit_SPIFlash library can be used to interface with the chip, and a strip of header is included so you can solder it on for breadboard use if desired.Features:Flash chip: W25Q16Capacity: 16 Mbit / 2 MByteInterface: Single-channel SPI onlyLevel shifting: Safe for use with 3V or 5V power and logicRegulator: Includes a 3.3V regulatorChip select: Includes a pull-up on CSMemory access: Can be addressed as a flat memory spaceFilesystem options: Can be formatted with littleFS or FATArduino support: Works with the Adafruit_SPIFlash libraryIncluded hardware: Comes with a bit of header that can be soldered in for breadboard useSpecifications:Flash chip: W25Q16Capacity: 16 Mbit / 2 MByteProduct Dimensions: 20.3mm x 17.7mm x 3.5mm / 0.8\" x 0.7\" x 0.1\"Product Weight: 1.4g / 0.0ozA good fit for data logging, storing graphics or fonts, and adding a modest amount of external memory to Arduino and other SPI-based projects.","vendor":"Adafruit","product_type":"Flash Memory Breakout","in_stock":true,"options":[],"variants":[{"id":15547,"title":"Default Title","sku":"AF-5635","mpn":"ADA5635","price":7.04,"on_sale":false,"in_stock":true,"available_quantity":5}]}
