I haven’t used my drone in forever here since you need a „flying license“ now and the questions are a real bitch
Well, the licensing thing is a bit of a jungle. The EU should have somewhat harmonized regulations, and the FAA regulations in the US are quite similar — at least in theory. In practice, different countries (and states) may have different local regulations, and the registration process varies a lot from one place to another.
The EU used to be very relaxed with the regulations, but this has changed. As long as you fly a sub-250 g (8.8 oz) drone, it is enough for the operator to be registered. Above that limit, the operator needs to pass an exam (in most countries, but there may be national differences), and there are a lot of different rules regarding where, what purpose for, and what kind of drone can be flown. The professional operator exams required for heavier drones close to people need to be passed under supervision (i.e., not in the web).
(As a side note, I have passed the private pilot theories for small aircraft without any significant effort, but reading the local drone regulations required in the exam makes me doze off.)
Then there are all sorts of fees (operator registration, annual fee, drone registration), and these fees vary wildly between countries.
In the EU, small toy drones (< 250 g)mdo not need any license, unless they have a camera. So, as the Pixy has a camera, it requires operator registration and paying associated annual fees but no exam. All this, however, requires the drone has the relevant CE class marking (C0). If there is no such marking, the drone may only be used far away from other people as of January 1, 2023.
And, yes, if you happen to have, e.g., DJI Mavic 2, it does not have the CE marking. This puts it in the Open Category A2, which means it must not be flown closer than 50 m from people, effective January 1st, 2023.
Mess? Yes. Some of the information above may be inaccurate or false, and even the interpretations are changing. Check with your local authorities. The key message, however, is that even using the Pixy will — with current interpretation — require some paperwork.
