7seg Click Board
The 7seg Click Board is an accessory board that allows user to add 2-digit seven-segment display to the device. This compact board includes two on-board 74HC595 8-bit serial-in, parallel-out shift registers as well as two seven-segment displays. The 74HC595 shift register has an 8-bit storage register and an 8-bit shift register. The data is written to the shift register serially, then latched onto the storage register. The 7seg click uses the Serial Peripheral interface (SPI) to communicate with the target board microcontroller. The board is designed to operate using a 3.3V or 5V power supply, selectable by an SMD jumper. The power indicator LED is available on-board.
The 7seg click is an ideal choice for adding popular 7-segment display to the device while using only 4 microcontroller pins. The green LED diode denotes the status of the power supply.

IC/Module: 74HC595 8-bit Serial-In, Parallel-Out Shift Register
74HC595 is an 8-stage serial shift register that feeds an 8-bit D-type storage register with parallel 3-state outputs. Separate clocks are provided for both the shift and storage register. Both the clocks, i.e., shift register clock (SRCLK) and storage register clock (RCLK), are positive-edge triggered. When connected together, the shift register always is one clock pulse ahead of the storage register. .
7seg click features a J1 SMD jumper, which enable the user to switch between 3.3V or 5V power supply. By default, J1 jumper is soldered in 3.3V position.
