MikroElektronika RTC 18 Click
Overview
RTC 18 Click shield is built around the Micro Crystal RV-3032-C7 temperature-compensated real-time clock (RTC) module. The module offers I²C communication, integrated timekeeping with leap year support, alarm and interrupt features, and a battery backup switchover circuit.
The RTC is designed for high accuracy (≈ ±0.22 s/day) and extremely low power consumption, allowing it to retain time using a small backup battery when main supply is removed.
More information about the shield can be found at Mikroe RTC 18 click [1].

Requirements
The shield uses a mikroBUS interface. The target board must define
a mikrobus_i2c and mikrobus_header node labels
(see Shields for more details).
