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 7seg click 2 3 1. Introduction 4. Essential features 7seg Click with its 74HC595 ICs gives additional seven-segment displays to your design. The 74HC595 IC contains an 8-bit serial-in, parallel/serial-out shift register as well as 8-bit storage register. The storage Turn the board upside down so that Turn the board upward again. Make sure registers has parallel 3-state outputs. bottom side is facing you upwards. Place to align the headers so that they are Separate clocks are provided for both the shorter parts of the header pins in both perpendicular to the board, then solder the shift and storage register. Shift register soldering pad locations. pins carefully. has a direct overriding clear input. 7seg Click is an accessory board in mikroBUS form factor. Its a compact and 3. Plugging the board in easy solution for adding seven-segment click display to your device. It features two Once you have soldered the headers your 74HC595 8-bit serial-in, parallel-out shift board is ready to be placed into desired BOARD register modules as well as two seven- mikroBUS socket. Make sure to align the www.mikroe.com segment displays. 7seg Click communicates cut in the lower-right part of the board with target board via SPI interface. The board with the markings on the silkscreen at the 7seg click Manual is designed to use 3.3V and 5V power supply. mikroBUS socket.
