The Microduino-RTC is a real time clock module based on NXP CMOS PCF8563. RTC module uses TWI/I2C interface for communication. Data can be backed up with the additional AT24c32 EEPROM. With an onboard capacitor, the module can keep timing for minutes after power-off since the PCF8563 adopts an external crystal and a capacitor as well as an interrupt input which can trigger the interruption periodically.
Based on PCF8563 clock chip with century mark, second, minute, hour, day, week, month and year.
Use the IIC interface to communicate with the Core/Core+ module.
Use EEPROM AT24C32 with I2C interface.
With a low-power clock chip and the typical current value is 0.25μA.
With a super capacitor, the clock will keep running after power-off.
Open hardware circuit design and Arduino compatible programming development environment.
With a uniform Microduino interface standard and rich peripheral modules, it can easily connect with other Microduino modules and sensors.
2.54mm(0.1 inch) pin pitch, compatible with bread boards and pegboards.
