The schematic(v1.1) of Duo S doesn't seem to match the actual board, especially in the WiFi section

In the schematic, the wifi chip is AIC8800D40, and components in RF circuit also seems different.

the real chip is AIC8800D80, and the capacitors and inductors in the RF circuit are noticeably different too. Did I miss the updated schematic? Is there a new version I haven’t found?

Here they mention at least two versions of the board: v1.1 and v1.2.
Mine are v1.2 with AIC8800D80

This document must be for v1.1, submitted issue #17.
