Specifications

It has been tested and can be connected to a 5V power supply.

Hardware Interface

1. Connect the W25Q64's Vcc pin to 5V on the development board.
2. Connect the W25Q64's GND pin to the development board's GND.
3. connect the CS (chip select) pin of the W25Q64 to a digital pin (e.g., pin 10) on the development board.
4. Connect the W25Q64's CLK (clock) pin to pin 13 (SCK) of the development board.
5. Connect the W25Q64's DI (Data Input) pin to pin 11 (MOSI) of the development board.
6. Connect the DO (data output) pin of the W25Q64 to pin 12 (MISO) of the development board.

Usage Method

Install Library

1. Open “Tools” > “Manage Libraries” in Arduino IDE, search for “SPIMemory” and install this library.
