CHUWI N4100 serial n. "...20 03..." and HiPen H6

Hello! Yesterday I bought a CHUWI UBook N4100 with a serial number “…20 03…”.
I didn’t know this! I also bought a HiPen H6. Now I cannot configure this pen! What is the qualitative difference between a CHUWI UBook N4100 whit a Serial N. “…20 03…” and the same model but with a Serial N. “…20 06…”?
I don’t want to buy an H3 pen because it has lower pressure levels!!!
Can you help me?
