I’m trying to free up my Pi 3b which is overkill for a PiHole with Unbound DNS and am looking to try something other than a pi zero. What are your recommendations! A few brands that come to mind are LibreComputer, NanoPi, BananaPi, and OrangePi. Bonus points if it’s possible to set up with POE!

The nanopi R2S looks like a decent option however is uses a broadcom chip. Could that be problematic? https://www.friendlyelec.com/index.php?route=product/product&path=69&product_id=282&sort=p.price&order=ASC
