Look at the green circuit board. You will see white silkscreen text. Search for the largest text block. It should clearly say H3Q44V30. Sometimes it appears as H3-Q44-V3.0 or similar.
Important: There is a variant called H3Q44V30-L or V3.1. If you have that, the WiFi chip differs slightly. We will address this in the driver section.
