As I already mentioned, I planned to have a RFM12B shield for the micro IoT gateway. Here is how it is looking, rendered in 3D, still work in progress, but the idea is clear. I wanted to keep the shield top for other expansions, like a micro SD card slot, but I am still thinking about it. The shield will be attached with extra long headers. The board is slightly larger than the uIoT gateway because of RFM12b’s size.
