Nope. I think a big difference is that I am not worried about lightning services. lnd might be dropping out all over the place, but I wouldn't notice, unless it also drops electrs. I think lnd is technically supposed to be running on it, but there's no channels, zero balance in the ln wallet, no need for it to actually do anything.
So I had RTL installed on there. Opened it up, it says it can't connect to LND server, so chances are, LND is down. Sparrow is connecting to my private electrum server just fine, so that appears to be working, and balances are current. I even have an electrum wallet with some random small balances in it, and that shows up fine in Sparrow.
So, good enough for me. I don't need to run lnd on my node for anything I'm doing right now. If I did, maybe I would choose something better than an rpi.
