+# K0501W
+
+This board appears for example in the Davuaz Da-K6501W switch.
+
+It is designed similarly to Hi-K0402WS. However, there are a few 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
+
+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".
+
+## PCB pictures
+
+The board is marked `PCB-K0501W-V2.0 DIP-K0501WS-V2.0`.
