Review on Geekworm Raspberry Embedded Compatible Expansion by Carl Mayes

Installed on a 2GB Pi 4. The heatsink is touching the RAM with the thermal sink installed. The processor does not touch. There is a visible gap and that is worrying. Would have preferred another piece of aluminum or acrylic for the bottom cover. As with other plugs of this type, the hole for Poe plugs is too small for a standard 2x2 socket. If you are using a poet's hat, you have a choice of sanding the plastic part of the head to fit, or using a file or dremel to open up the hole. It was low enough in profile that the hat I was using could fit without extensions, so instead of filing the female connector and possibly ruining it, I enlarged the hole with a Dremel tool.
