It is possible to setup a blockchaine project node on a raspberry3 and be rentable? What project do you recommend?

I wouldn't know how a Raspberry pi or the one you mentioned work because I haven't used any before. But as long as the raspberry has the capacity to run linux, windows or any other supported OS, then I'm sure you can run a node on it. If you're just running a full node without participating in consensus, then that's even better.

Regarding your question for possible projects to run the node for, you'd have to do your own research because it needs to be an incentivized Node otherwise,  you're just running it out of the goodness of your heart.  Do check out Avail, Espresso and a few others. You can use DeFi Llama to help with the research process.

honestly depends on what blockchain, usually running node or an archive node only requires 4 cores (slow can still compensate) and also big ass storage, if your raspberry could be attached with at least SSD sata of few terabytes then I guess it can run, also if what you mean by renting is making RPC node where people could rent it based on rates or tokens, then I guess it could work but the request called might be something you need to think about raspberry is low in power but also slow.
its entire different thing with running node and being a validator though, usually raspberry will not suffice, even intel xeon 3rd generation and older are considered slow in this regard.
if you truly want to start a renting business its better if you could at least invest in some server pc instead of raspberry pi, this thing only suited for small hobby projects.
even better if your server pc supports intel SGX 2.0 as well as having many computing power that is many cores and big rams, this will be more beneficial in the long run.

Rapberry 3 has a few models, and a difference in hardware is crucial.

512 MiB RAM is really tough. An operating system uses the memory on its own, let's say 128 MiB. Also you need some memory for a disk cache and whatever the OS periodically does in background, let's say plus 128 MiB. Perhaps you'll want to add I2P and/or Tor on top of that.

With 1 GiB RAM, you can run Blacknet node (https://blacknet.ninja/download.html) and use it for solo staking... until we implement a hardfork with zero-knowledge proofs, then it's too likely to not fit too.
