 This board appears for example in the Davuaz Da-K6501W switch.
 
-It is designed similarly to Hi-K0402WS. However, there are a few differences:
+The general design of the board is similar to Hi-K0402WS V3.0.
+However, there are several differences:
 - One SFP port is replaced by a RTL8221B 2.5G PHY
 - Only one LED is populated for the SFP port
 - No mode switch and only one flash chip
-- Like earlier revisions of the K0402W(S) board, there is no UART
+- Older design using RTL8372 instead of RTL8372N (which also means different GPIO and LED configuration)
+- Like earlier versions of the K0402W(S) board, there is no UART
 
-Even though board looks very similar to K0402W(S), the actual GPIO and LED configuration is quite different.
 All ports and LEDs are supported.

 Installation is possible using a flash programmer.
 The BoyaMicro 25Q16BSSIG flash chip is supported by flashprog with chip name "B.25D16AS/BY25Q16BS/BY25Q16ES".
