Description: This is a breakout for the SOIC version of the 74HC595 shift register IC. Clock in data and latch it to free up IO pins on your micro. All pins from the IC are broken out to standard 0.1" spaced headers. The Serial in and out pins are on opposite sides of the board with the remaining pins carried over so that multiple shift register boards can be chained together.

Have been trying for months to get the max 7219 to work in a linear LED display with the Arduino Uno rev 2. But the 7219 is made to be used in a matrix or a 7 segment display. It was thought the fact that the 7219 handled 64 LEDs and the 74HC595 did eight gave the 7219 a great advantage. But breaking the 7219 out created a rat’s nest of wiring. Whereas the 74HC595 with Digikey’s S5482-ND female 7position right angle connector with the S1111E-07-ND 7 position right angle connector modularized the construction making testing and assembly of a line of 340 LEDs much simpler.
Makes experiencing with 74595 SiPo mcuh easier, you don’t need to check datasheet all the time whether you made right connections, this chip can be quite confusing at a start, but very handy once you get hold of it. These can be daisy-chained if 8 O/P isn’t enough. Good extra about this product is that it’s breadboard friendly, only takes quite chunk off from prototyping space, but it’s worth it. Underside of pcb is flat, so you can also install it without spacers needed, only there are tracks there so beware of S/C if you place this on metal surface. That said though, pcb quality is great, so S/C won’t be issue at least anytime soon
Price is bit pricey if you need only to use this, but makes job easier to use this board
