It seems that all parts are fitted corretly. The ECHO-Test works know but i have problems with my DIO-Board at all. After connecting these two parts nothing happens. But when i make a shortcut between to points of my ATMEGA8538 both LEDs goes on. Also when i make a shortcut between R2 and J2 the green LED works well...So the connection is available but anyway it does not work
