| + | Developing various useful items for model railroad is my hobby.\\ | ||
| + | But sometimes somebody else made something, that is too good to develop it again.\\ | ||
| + | This is one, I found here:  http:// | ||
| + | I liked it such that I designed a board for it, and called it GCA204.\\ | ||
| + | Firmware is all available on the network.\\ | ||
| + | There is hardly anything further to describe about it, all is already readable :\\ | ||
| + | **[[http:// | ||
| + | This board is no longer available.\\ | ||
| + | Look at GCA214 for next development.\\ | ||
