GCA204 Railcom display
Sometimes, there's no need to develop something...
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://usuaris.tinet.cat/fmco/home_en.htm
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 :
on Paco's Official Website.
This board is no longer available.
Look at GCA214 for next development.
