+===== Modification of PCB rev. 1.0 =====
+In the initial PCB, the blue LED channel is connected to PD7 (OC2A, pin21). To use the same code as for the RGB Dimmer, this needs to be rewired to PD6 (OC2B, pin20). Cut the connection at the bottom of the PCB and make the new connection with a wire.
+The status LED has to be rewired from initial PB2 (pin3) to PD7 (pin21), also to use the same code as in all other devices for the status LED. This can be done easiest by connecting the resistor R1 to a wire and connecting the wire to PD7.
+In future PCB versions, this shall be changed in the schematic and layout.
+To perform the modification, cut the PCB tracks on the marked positions and connect them to the other pins with patch cables.
