The ExtensionBlock is an add-on board for the Raspberry Pi and compatible System-on-Chip platforms. It is a three-way distributor for the 2×20 GPIO pin header. You stack it on top of the existing 2×20 pin GPIO header. It allows you to stack two full-size HATs side-by-side onto the Raspberry Pi. In addition to the pin headers for the HATs, the ExtensionBlock has a third 2×20 pin out so that you even have access to the GPIO pins when two HATs are installed. This should give you a maximum of comfort during development and debugging of your project.
