Gravity: 74HC595 ShiftOut Module (8-Bit Digital Output Expansion)

The Gravity: 74HC595 ShiftOut Module is an 8-bit digital output expansion board designed to increase available GPIO capacity on microcontrollers. It provides an efficient serial-to-parallel solution for makers, students, and engineers looking to drive multiple LEDs, relays, and displays using minimal control pins.

Serial-to-parallel 8-bit expansion

Powered by the reliable 74HC595 shift register, this module converts serial microcontroller data into eight parallel digital outputs. Built-in output latches and three-state control allow simultaneous updates across all eight channels while occupying only a few GPIO pins.

Daisy-chain multi-module scalability

Multiple boards can be cascaded in series via onboard IDC6 connectors to massively expand output channels without demanding extra pins from your host controller. This daisy-chain capability suits larger projects such as high-density LED matrices and complex relay switching networks.

Broad microcontroller compatibility

Operating at 5V, the module interfaces smoothly with Arduino, AVR, PIC, and 51-series development platforms. Standardised IDC6 input and output headers keep project wiring tidy and simplify integration with standard expansion shields.

Compact form factor specifications

Measuring a compact 41 x 22 mm, the module integrates easily into space-constrained robotics and embedded enclosures. Each pack includes one 74HC595 ShiftOut Module ready for rapid prototyping.
