Which Ubook do i have?

Hey i bought a Ubook two month ago and i am not sure which one i actually bought the new one or the old one, to know which HiPen i need to buy.
Its a TYPE: CWI509 with the Serial Number: ubook Q256G20032…

Actually i bought a 2020 ubook version so i thought i have got the new one, but somehow my HiPen H6 isnt working (tried two different) may be its the old one and i need the H3 HiPen. Anyone knows which one i have?

I would appreciate every help!

Well i solved this problem by myself, for people which will have the same problem - if u also got this kind of serial number = you have the old u book and you need the H3 Pen!
