This terminal block expansion hat for Raspberry Pi offers securely and stably fitted connections for your projects.
All GPIO pins are broken out to terminal blocks. The terminal block is labeled with high-quality color silkscreens, clear and durable. Besides, it has onboard level indication LEDs for corresponding pins below the blocks, which allows users to directly view the pin status when operating GPIO so as to conveniently do testing, debugging, and post-maintenance.

Jargon buster
Plain-language definitions for the technical terms used above.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- Terminal block
- A connector used to join wires together in a neat, removable, or serviceable way. For this product, it helps split one power input into several outputs without soldering.
