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 RTC4 click 2 3 4. Essential features RTC4 click has an integrated backup energy source that maintains a charge with an onboard coin cell supercapacitor. Being a 1-Wire click board , RTC4 click can operate in a microLAN network (a network of 1-Wire devices that are all associated with a master Turn the board upside down so that Turn the board upward again. Make sure device). To indentify it in a network, the the bottom side is facing you upwards. to align the headers so that they are DS2417 IC has a factory lasered and tested Place shorter pins of the header into the perpendicular to the board, then solder the 64-bit registration number. RTC4 click is 1. Introduction appropriate soldering pads. pins carefully. ideal for applications that require realtime clocks, calendars and programmed alarms. RTC4 click carries DS2417, a real time clock/ calendar with a 1-Wire MicroLAN interface and a programmable interrupt for system 3. Plugging the board in output. The clock frequency is derived from an click onboard 32.768KHz oscillator. The clock has Once you have soldered the headers your an accuracy of +/-2 minutes per month at a board is ready to be placed into the desired BOARD 25 degrees Celsius temperature. Depending mikroBUS socket. Make sure to align the www.mikroe.com on the position of the onboard jumper, RTC4 cut in the lower-right part of the board with click communicates with the target board the markings on the silkscreen at the MCU either through mikroBUS AN or PWM mikroBUS socket. If all the RTC4 click manual ver 1.01 pin (here, GPI01, GPIO0), plus the INT pin. The pins are aligned correctly, board is designed to use either a 3.3V or 5V push the board all the way power supply. into the socket. 01000000789458. Code examples 5.
