74HC165 Breakout Board
The IC 74HC165 can read an input of 8 parallel lines and produce a 8-bit serial output.
Multiple shift registers can be cascaded so it's a great way to increase the number of inputs on a micro-controller.
On one side of the breakout board is a serial-in connection and on the opposite side is a serial-out connection, making cascading the boards easier.
The breakout board uses standard 2.54mm pitch headers.
Operating Voltage:2V to 6V
If you need more outputs, the 74HC595 is an 8-bit Serial-in/Parallel-Out shift register.
