I see now that Raspberry Pi model 3B has new model 3B+
I also read the comparison and see that:
“Performance increases are always welcome and while there are always those in search of that bit extra processing power or network throughput, Power-over-Ethernet is almost certainly the hottest feature with the Raspberry Pi 3 Model B+. It may at first seem like a niche capability, but the benefit of being able to run a device with network and power delivered by a single cable — and without a mess of power supplies and power cables — is not to be underestimated.”
However, I am not so sure that 3B+ is compatible with the requirements and the documentation outlined in DWM1001 Gateway Quick Deployment Guide.
So what should I get? 3B or 3B+ ?
