2. Soldering the headers Before using your click board, make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 RTC3 click 2 3 4. Essential features RTC3 click has an integrated trickle charger that maintains a backup charge through with an onboard super capacitor. The board is ideal for applications which require real- time clocks, calendars and programmed Turn the board upside down so that Turn the board upward again. Make sure alarms. It counts seconds, minutes, hours, the bottom side is facing you upwards. to align the headers so that they are date of the month, month, day of the week, Place shorter pins of the header into the perpendicular to the board, then solder the and year with leap-year clock function with appropriate soldering pads. pins carefully. four year calendar. 1. Introduction 3. Plugging the board in RTC3 click carries BQ32000, a real time click clock/calendar with automatic switchover Once you have soldered the headers your to backup power supply. The clock frequency board is ready to be placed into the desired BOARD is derived from an onboard 32.768KHz mikroBUS socket. Make sure to align the cut in www.mikroe.com oscillator. RTC3 click communicates with the lower-right part of the board with the the target board microcontroller through markings on the silkscreen mikroBUS I2C lines: SCL, SDA. In addition, at the mikroBUS socket. RTC3 click manual ver 1.00 the INT pin serves as a configurable interrupt If all the pins are aligned output. The board is designed to use a 3.3V correctly, push the board all power supply only. the way into the socket. 01000000744978. Code examples 5.
