W25Q32 FLASH Storage Module SPI Interface 4Mbyte
This unit makes it easy to store your data and the data will not be lost if your microcontroller is powered down or lost power.
This module uses your microcontroller’s SPI interface and thus will only require one digital pin to work. Please note that the max volts for this module are 3.6V. More than that will damage the chip, if your microcontroller board have a 3.3V output it will work perfectly with this module.
