DFRobot Gravity: Shiftout Module

DFRobot Gravity: Shiftout Module is based on the Texas Instruments 74HC595 8-bit serial-in, serial, or parallel-out shift register with output latches. The DFRobot module can control eight outputs simultaneously while only taking up a few pins on a microcontroller. Link multiple registers together to extend the output even more. It's also applied to 51, AVR, PIC, and other microcontrollers.
