A dcc block detector based on STM32F030 and measure current over diode-drop
#This detector is usefull both for N-Scale and H0-scale. A SMC diode of 5A can handle alot of current. For N-scale its possible to use regular pin header at IO1, IO2 (max 3A). For HO scale i recommend screw terminal to handle more current.
#Note Another board with a MCU is needed to translate from uart to other protocols.
