I bought the "Hanmatek" branded version of this scope (HO52, equivalent to the HDS242). I was expecting it to the be the same as the OWON model, but there are a few unexpected differences.
From the outside it looks the same but with a slightly different enclosure (it tapers at the bottom and green rubberized material goes all the way around the sides).
The System > About screen lists the Hanmatek model name, but also FW v8.3.0. This doesn't match any known firmware version from OWON.
When I open it up there are more noticeable differences.
First, the board stamp says "HDS200-MAIN-V3.3 2023-2-2". This matches OWON boards, except the HW version/date is newer than others shared before (most recent I've seen is 3.0 dated from 2021).
Serial number is 2309xxxx, so I assume it was assembled during the first week of March 2023.
The other big difference is that instead of a removable 18650 Li-Ion battery carrier, it instead has a 124065 Li-Po 4Ah battery pack soldered to the board. Interestingly, while the positive lead is soldered to the original battery carrier pad,
the negative lead is soldered directly to the 3130 battery protection SMD output pins (I assume that's what it is - the face of the package is slightly melted

- but its in the same place as other rev boards).
I'm unable to check the Hanmatek website about firmware updates. Since it was assembled so recently it's possible this includes the changes added in OWAN's May 2023 FW update. I'm not sure if future FW updates will have to be released by Hanmatek, or if it will be possible to use the files provided by OWAN. It remains to be seen if the HW v3.3 board is exclusive to Hanmatek or if OWAN will begin assembing their own units using it.
Has anyone else encountered this HW revision? Has anyone had success getting FW updates for the Hanmatek rebranded units (from either Hanmatek or OWAN)?
