 ### Notes
 * `TX Disable`-SFP2 and Button `K1` share the same GPIO pin via `R105` and `R85`.
-  But with `R88`, `TX Disable`-SFP2 can be mapped to `C4`.
+  But via `R88`, `TX Disable`-SFP2 can be mapped to `GPIO36`.
 * `TX Disable` pull-down resistos on both SFP are to low to drive by the SOC.
   We need to make a `Best`-BOM variant so we can use all the featues.

+Note:

+* [^1]: LEDs are found by just plugin a RJ45 connector and see with cmd `gpio` the status change. But the bit pattern for port 1,2 are diffrent from port 3,4.
+* [^2]: Only on the unmanaged verions are `R10` and `R268` placed. But the very low pull-down resistor `R10` & `R262` prevent to SOC to drive does pins. A mod is needed.
+* [³3]: GPIO54 is used for the reset-button. `T-R85` is placed.
