Boost your projects with added memory!
This is a pack of 3 MEMORY MODULES:
Use this module to use Micro SD and MMC cards with ease.
Note that the mainboard has to support the FAT and FAT32 file system. Size limit is 2GB. This Micro SD module makes use of the SPI serial access.
On board is a buffer IC CD4050 for high-speed communication.
Moreover, LEDs provide indication for both power and activity operation.
Module connections are also indicated at the bottom side of the board.
EEPROM Data Module – AT24C256
For storage of data in for your projects this I2C EEPROM data module is your best choice.
This module is based on the EEPROM chip AT24C256, which has 256k bit capacity. It communicate with Arduino via I2C bus, and helps you do much more data storage easily. A DIP switch is provided for I2C address setting.
RTC (Real Time Clock) DS1307 module
This is a real time clock (RTC) module based on DS1307 IC that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Applications include data-logging, clock, timers and alarms.
The DS1307 can be easily connected to the Arduino with I2C bus interface.
