Hi,
I'm interested in the Raspberry Pi. I primarily want to use it to learn as well as send my data from the Atlas to other places besides WU. Currently I upload via the Access to WU and have no problems. I just would like to perhaps have more capabilities.

I've been looking at the various Pi kits and would like to know if one brand kit is better than the other? How much RAM do I really need? Basically, which one of the kits should I buy based on my intended use? I'm assuming that being a NOOB to the Rasperry Pi, I'd be better off with a complete kit rather than individual components. From my preliminary searching, it seems like the new Pi 4 may be the way to go. I have had some linux experience, but that was probably 5 - 10 years ago.

Thanks for any assistance.

Simple answer. Get a Pi 4 :D
There is several advantages of using a 4. RAM been one of them and thats a major plus, Also the separation of the BUS and 1Gige Ethernet.

Thanks for your response.

Not to disagree (for initial development you can never have enough CPU and RAM) but the RPi4 does run hotter and takes more power than some of the older models.
What I'd recommend is to get an RPi4 and build up whatever you want on that. Then look at what the CPU and memory utilisation are like and see if an older model will do the trick - they generally run cooler and take less power.
Depending on how you intend to use the device, these might be useful considerations.
You can then use the RPi4 for the next project....
Regardless of which device you get, spend a bit of time looking at ways to reduce/eliminate writes to the SD card as this can be the 'archillies heel' of the system, especially if you want it to be running unattended for a long time. (I have a RPi Zero W that monitors my weather station and acts as a web server - it has been running for a number of years without a problem as I have the data stored on a NAS drive and the logs etc. are all written to memory disk; virtually no writign to the SD card at all.)

Thanks for your thoughts. I have read that the RPi4 does run a bit hotter and requires more power than older models. If I go that route, I plan on getting a complete starter kit with a decent case that has a cooling fan. At the present time, I mainly want to use it for my weather station so I may rethink this and go for an earlier generation unit. I'll do more research before I leap into this. Thanks again.
