{"title":"Adafruit SPI FLASH Breakout - W25Q64 - 64 MBit / 8 MByte","handle":"adafruit-spi-flash-breakout-w25q64-64-mbit-8-mbyte","url":"/products/adafruit-spi-flash-breakout-w25q64-64-mbit-8-mbyte","description":"The Adafruit SPI FLASH Breakout features a W25Q64 chip providing 64 Mbit (8 MByte) of non-volatile flash storage over a standard SPI interface. It's ideal for adding compact, low-power external storage to microcontroller projects — perfect for files, images, fonts, and audio clips when a full SD card is more than you need.\n\nUnlike QSPI breakouts, this board includes level shifting so it works safely with both 3.3V and 5V logic, plus a 3.3V regulator and a pull-up on chip select. The chip comes blank and can be addressed as flat memory or formatted with a filesystem like LittleFS or FAT.\n\nKey Features\n\n\nW25Q64 Flash Chip – 64 Mbit (8 MByte) non-volatile SPI flash storage\n\nSPI Interface – Single-channel SPI with level shifting for 3V or 5V logic\n\n3.3V Regulator – Onboard regulator and CS pull-up for clean operation\n\nBlank Chip – Address as flat memory or format with LittleFS/FAT\n\nBreadboard-Friendly – Includes header for breadboard use\n\n\nAlso Consider\n\n\nSPI FLASH Breakout W25Q128 – 128 Mbit / 16 MByte – Double the storage capacity\n\n\nIdeal For\n\nData logging and sensor storage\nStoring images, fonts, and audio clips\nAdding external memory to older 5V microcontrollers\nProjects that need more than EEPROM but less than an SD card\n\n\nPackage Contents\n\n1× SPI FLASH breakout board (W25Q64)\n1× Header strip\n\n\n\nNote: The chip comes blank with no wear-leveling subsystem. You are responsible for flash management or filesystem formatting.\n\n\nResources\n\nAdafruit SPIFlash Arduino Library\n","vendor":"Adafruit","product_type":"","in_stock":true,"options":[],"variants":[{"id":1391,"title":"Default Title","sku":"AF-5636","price":8.09,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":1,"option1":"Default Title"}]}
