Re: Communication with multiple arduinos

Must it be a Arduino? Do you know ESP8266/ESP32 boards? there you could just send it over W-lan. How do you send your data wireless to the Pi (not decided yet, or not mentioned). Are your Arduinos planned to run on battery?

Re: sd card characteristics

IMO only A1/A2 rated cards are worth in those days.. The price difference between outdated slow card and an A1 rated one in minor and for sure not worth it. You may be correct. My problem is that, for a lot of uses, I don't need a large card. I'm running many Pis on 8GB cards, and those simply don'...

Re: Next raspberry ethernet?

So, none of them hit 1000mbits/s then. As I said. Everyone knows that the Pi is limited to its USB speed and that these devices are faster. That's not the point. The point is that all these devices are GigE, including the Pi, independent of the throughput. C'mon.. there's a significant difference b...

What are you not getting out of it ? Is it latency, response time, transferrate ? Or is it something else ? transfer-rate when needed.. If I don't care I go for an SBC without GbE. If I would ever buy a 3b+ I would probably cap it to full speed cause I don't want to deal with flow-control.. When me...

If you have a full HD display but 2/3 of it is always black, do you call it fullHD? Just ask for a friend.. Yes. If it is a true HD display. It may be that the device driving it isn't capable of full HD, but that is not the point. (I'll skip the overscan issue here because that isn't "2/3 of it"). ...

If you don't want to learn new things.. Which not everyone does, and those who do often don't have the luxury of time to invest to do so.
