Review on ⚡ Effortless GPIO Connectivity: Alchemy Power Inc. Pi-EzConnect – Seamlessly Link Raspberry Pi 4, Pi 3, and More with GPIOs and Sensors by Jason Carranza

This HAT gives me a more convenient connection platform to test and use my Raspberry Pi projects without worrying about pulling the connectors out of the pins. I would have given it 5 stars but the connector badges on one side were partially obscured by my mount. Wasn't a big problem, the GPIO numbers were visible but the physical contact # was closed. The biggest problem I have is using it on my Raspberry PI 4. The HAT is preventing the fan from installing properly. I'm using my Pi as an SDR receiver and it generates a lot of CPU heat, so I need to design a side-mount fan to keep the CPU cool.
