Raspberry Pi Expansion Boards

Our versatile range of stackable expansion boards are designed to align with the HAT (Hardware Attached on Top) mechanical specification to ensure compatibility with a wide array of third-party Raspberry Pi HAT boards.

Our expansion boards work with every Raspberry Pi model featuring a 40-pin GPIO connector. This includes the latest Raspberry Pi 5, the compact Raspberry Pi Zero, and the unique Raspberry Pi 400. With our boards, you have the freedom to stack multiple modules, allowing you to tailor your setup to your specific needs. Whether you're looking to integrate analogue inputs, expand your GPIO input/output capabilities with up to 128 additional ports, establish serial RS232 communications, or add a real-time clock module, our boards have you covered.

Moreover, our expansion boards are not limited to Raspberry Pi. They are also compatible with other popular small board computers like the Asus Tinker Board, Orange Pi, and ODroid. This versatility ensures that you can enhance your projects, irrespective of the platform you choose.
