For when two (mini) HATs are better than one! A nifty prototyping tool for connecting multiple mini HATs to one Raspberry Pi. This HAT gives your Pi two sets of GPIO pins - very useful for attaching two mini HATs (or a HAT and a mini HAT) at the same time, great for prototyping, debugging or for connecting a mini HAT to other circuitry. Because it sits directly on top of the Pi it's also a tidy permanent mounting solution for projects that involve two mini HATs, we've included plenty of standoffs so you can keep them suitably secured. Features * 2 landing areas for mini HATs with pre-installed 40 pin male connectors * GPIO pins labelled with function and BCM pin numbers * 6 black metal PCB standoffs for HAT and mini HAT mounting * 8 mounting holes * Pre-installed 40 pin female connector for attaching to Pi's GPIO * No soldering required! If you're planning on using multiple mini HATs in your project, you'll need to check for GPIO conflicts - Pinout.xyz and pHAT Stack Configurator are useful for this! https://elecena.pl/product/22719103/hat-hacker-hat 2023-03-07 https://elecena.pl/product/22719103/hat-hacker-hat 2023-12-27 https://elecena.pl/product/22719103/hat-hacker-hat 2024-09-19 https://elecena.pl/product/22719103/hat-hacker-hat 2024-11-29 https://elecena.pl/product/22719103/hat-hacker-hat 2024-11-30 https://elecena.pl/product/22719103/hat-hacker-hat 2025-11-28 https://elecena.pl/product/22719103/hat-hacker-hat 2025-11-29
