Multifunctional GPIO Expansion Board with Screw and Jumper Caps Secure wiring and flexible configuration Screw terminals provide secure connections for power, ground, and GPIO signals, reducing the risk of loose wires during operation. Jumper caps enable quick configuration and routing changes without rewiring, supporting fast prototyping and testing. Broad compatibility and easy integration Designed to work with standard GPIO header layouts and a wide range of development boards, making it suitable for many projects and platforms. Simple, plugandplay design that fits into compact enclosures and varying project setups. Durable construction and reliable performance Compact form factor with robust connectors for repeated use in daily development and testing. Built with a durable PCB and quality connectors to ensure stable signal integrity during normal GPIO operation. Clear, practical attributes Function: expands GPIO access with secure wiring and configurable jumpers. Compatibility: suitable for standard GPIO headers across common development boards. Size: compact form factor ideal for tight spaces and portable projects. Material: durable PCB and quality connectors designed for longevity. Performance: reliable, repeatable connections for routine GPIO tasks. Use scenarios Prototype development and testing: quickly connect sensors, LEDs, and actuators to GPIOs; use jumpers to reconfigure signal routing as your design evolves. Education and tinkering: safe, handson practice with GPIO wiring and jumper configuration in a classroom or makerspace setting. Small automation and IoT projects: maintain a stable GPIO expansion for home automation, data collection, or device control in compact installations.
