Microduino-RTC Module is a Real Time Clock module based on NXP CMOS PCF8563.
+
 
−
RTC module uses TWI/I2C interface for communication.
+
Microduino-SD aims to read and write data of a memory card.
−
Data can be backed up with the addtional AT24c32 EEPROM.
+
 
−
With an onboard capacitor, RTC module keeps time for serveral minutes after power disconnected.  
+
 
−
PCF8563 uses external crystal, and can provide timer intterupt tigger.
