Block Diagram DISPLAY BOARD UTC/LOCAL HOURS MINUTES SECONDS 8 8 8 8 8 8 DISPLAY DRIVER MAIN BOARD MENU REAL TIME CLOCK MICROCONTROLLER BUZZER The clock consists of two modules, the main board and the display board. The clock was designed this way to allow the same main board to use different display boards which could vary in size. -
Page 19: Display Board Circuit Description
This device uses a 3 wire, I2C interface to communicate with the microcontroller. Connector J2 is the programming interface connector. This allows the firmware to be modified and the ability to reprogram the microcontroller. The CLK036 main board looks just like a Arduino Uno and can use the popular Arduino IDE. -
