RTC 21 Click is a compact add-on board that accurately keeps the time of the day. This board features the PT7C4311, an I2C-configurable real-time clock module with programmable square-wave output from Diodes Incorporated. The PT7C4311 includes time and calendar functions providing various information such as hour, minute, second, day, date, month, year, and century. It operates in a 24-hour format indicator, has automatic leap year compensation, and low power consumption, allowing it to be used with a single button cell battery for an extended period.
This Click board™ is suitable for various time-keeping applications, including daily alarms, metering applications, and others requiring an accurate RTC for their operation.

ABOUT CLICK BOARDS™
Click boards™ follow a modular prototyping add-on board standard invented by MIKROE, which revolutionizes the way users add new functionalities to development boards. Click boards™ enable design engineers to change peripherals easily, cutting months off development time. To enable hundreds of Click boards to be connected to the microcontroller or microprocessor, we have invented socket standard - mikroBUS™. This uniform connection interface allows you to connect any Click boards to a main board instantly. The company releases a new Click boards nearly every day at 10am, and many leading microcontroller companies including Microchip, NXP, Infineon, Dialog, STM, Analog Devices, Renesas and Toshiba now include the mikroBUS™ socket on their development boards.
MikroElektronika (MIKROE) is committed to changing the embedded electronics industry through the use of industry-standard hardware and software solutions. In 2011, the company invented the mikroBUS™ development socket standard and the compact Click Boards that use the standard to dramatically cut development time. Now the company offers 1300+ Click Boards – ten times more than competitors - and the mikroBUS standard is included by leading microcontroller companies such as Microchip, Renesas and Toshiba on their development boards. MIKROE defined MCU development add-on boards and socket standard called SiBRAIN, and display board and display socket standard - DISCON. MikroElektronika also makes the world’s widest range of compilers and additionally provides development environments, development boards, smart displays and programmers and debuggers.
