This ShiftOut Module uses a 74HC595 shift register to expand your microcontroller's output capability. Control 8 digital outputs while using only a few GPIO pins—and chain multiple modules together for even more outputs. A practical solution when your Arduino or Raspberry Pi project needs more digital outputs than available pins, without the complexity of I2C or SPI expanders. Key Features 8 Extra Outputs – Control 8 digital outputs per module Daisy-Chainable – Link multiple modules for expanded output capacity Minimal Pin Usage – Uses only a few microcontroller pins IDC6 Interface – Easy connection with ribbon cables Compact Design – Small footprint for tight spaces Specifications Chip – 74HC595 shift register Voltage – 5V Input Interface – IDC6 Output Interface – IDC6 Dimensions – 41 × 22mm Compatibility Arduino (pairs with Interface Shield) Raspberry Pi Other 5V microcontrollers Ideal For LED arrays and displays Projects requiring many digital outputs Relay control systems Expanding GPIO on pin-limited boards
