h1. Eval

* Big LEDs to test outputs / Backlight-PWM

* Amplified Buzzer to test buzzer output directly on MCU

* PWM output to test buzzers; 3V; normal and amplified

* Test for CANBus-cables;

** MCU with 4 inputs

** 4 outputs to control which line to be tested to detect shortcuts

** 4 outputs for LEDs to indicate errornous wire

** How detect shortcuts

** Button to reset

* Durchgangsprüfer ( buzzer-out / Buzzer-in )

** Do i really need this? Dont want to setup an multimeter

** Does not cost much

** The signal is already there. It might be usefull to inspect the board

h2. Buchsen

* GND
