I tend to power my devices via a simple USB phone-charger.
Like the parent I have a few temperature/humidity sensors dotted around the house. Using a PI would be overkill and I'd have to keep the system packages up to date, worry about failing storage-device, etc.
Yep. Most have a micro-USB connector which supplies power, and handles uploading/logging. So when you're done debugging, you just need a phone charger with a long enough cable.
