+===== Description =====
+This central station is a follow-up from WIO_Prog1.\\
+Since most central station now are working with a dc power supply, that is needed for this one too.\\
+With two built-in 3,5Amp output drivers, one will have a to use these outputs together on your\\
+railroad tracks, both wih their own section.\\
+In that case you are not working with 7 Amp power on the rails, but with two sections with 3,5 Amp each.\\
+The ouput is electronically fused, so short circuit will imediate switch off total power.\\
+WIO_prog2 can be controlled from Rocrail via WIFI, USB and CAN. \\
+The used firmware is the same firmware as for all WIO units, using Lolin D1 or D32 (Arduino related) modules.\\
+ \\
+===== Loco Node-ID====
+DCC Locomotives must be set IID to WIO and Node-ID to the ID of the WIO-Prog2.\\
+ \\
+===== further info =====
+Since this board is using same firmware as other WIO related units, the complete concept\\
+is explained in one page.
