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 RTC 5 click 2 3 4. Essential features For storing data, the chip onboard RTC5 click has 64-bytes of battery-backed SRAM and 1 kbit of EEPROM, along with 128 bits of protected space for storing a unique ID. The SPI interface has clock speeds of up to 5 MHz which is enough for a millisecond alarm. The clock/calendar automatically compensates Turn the board upside down so that Turn the board upward again. Make sure for leap years and months shorter than 31 the bottom side is facing you upwards. to align the headers so that they are days. The interrupt pin can be used to set up Place shorter pins of the header into the perpendicular to the board, then solder the alarms or events. appropriate soldering pads. pins carefully. 1.
