This breakout makes it much easier to prototype with external QSPI flash on modern microcontroller platforms such as RP2040, ESP32, RT10xx and STM32 designs. It converts a wide 8-SOIC flash package into a breadboard-friendly 0.3" wide DIP format, which is handy when you want to test different flash sizes or add extra storage to a project.

The board is fitted with a W25Q16JVSSIQ flash memory chip, providing 16 Megabits of storage, also described as 2 Mega-bytes. It uses 3.3V power and 3.3V logic only, so it should be paired with compatible hardware.

The Q suffix on this chip means the Quad Enable bit is permanently set in the status register, so it is ready to use in QSPI mode straight out of the box. If you are using it in standard SPI mode, the hold and write protect pins do not do anything, so they should be connected to 3.3V. Adafruit also provides support through the Adafruit_SPIFlash library for Arduino, and the chip has a TOML definition file for use in CircuitPython board definitions. A strip of header is included for soldering on and plugging into a breadboard, or for replacing an existing socketed SPI flash DIP chip.

Specifications:

Product Dimensions: 11.2mm x 10.1mm x 3.5mm / 0.4" x 0.4" x 0.1"

A useful option for adding removable external code or asset storage during development, especially on 3.3V boards that support SPI or QSPI flash.

Jargon buster

Plain-language definitions for the technical terms used above.

breakout: A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
CircuitPython: A beginner-friendly version of Python designed to run directly on microcontroller boards. If a product supports CircuitPython, you can often program it by copying code files onto the board rather than setting up a more complex toolchain.
ESP32: ESP32 is a family of low-cost microcontroller chips and modules from Espressif with built-in WiFi and Bluetooth. They support programmable firmware and over-the-air updates, and are commonly programmed with toolchains such as the Arduino core and ESP-IDF.
Flash memory: Flash memory is non-volatile memory that retains stored data even when power is removed, and can be erased and rewritten in blocks. It lets data such as firmware, settings or saved records persist across power cycles.
microcontroller: A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
RP2040: The RP2040 is a dual-core Arm Cortex-M0+ microcontroller chip from Raspberry Pi, used on many maker boards and offering programmable I/O, multiple GPIO pins and reasonable processing speed. Code and accessories built for that chip should work where RP2040 compatibility is listed, though demanding tasks such as reading a camera can require careful pin allocation and timing.
SPI: A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
STM32: STM32 is a family of microcontroller chips commonly used in embedded electronics. Knowing a product uses an STM32 can help when looking at firmware updates, pin connections, or low-level serial control options.
