MIKROE-6964

RTC 27 Click Add-On Board

Mikroe RTC 27 Click Add-On Board provides low-power real-time clock and calendar functions for embedded systems that need accurate time tracking, alarm events, watchdog timing, and timestamp capture. This board is based on the NXP PCF8525 nano-power CMOS RTC and communicates through an I²C interface, making it suitable for host systems that support the mikroBUS™ standard. The device supports calendar and time data down to 1/100-second resolution, programmable alarm and watchdog interrupt functions, battery backup with automatic switch-over circuitry, and two interrupt outputs with onboard jumper routing options. The RTC 27 Click also includes ClickID for automatic board identification and Click Snap for reduced-size implementation during later prototyping stages. Mikroe RTC 27 Click Add-On Board targets portable instruments, wearable devices, industrial systems, and IoT applications that require reliable timekeeping with low power use.
