Insisto en lo que ya dije anteriormente: el límite máximo del "Arduino Motor Shield" es de 18V. No lo digo yo, lo dice la documentación oficial
Pestaña "Documentation", apartado "Power" tercer párrafo: https://store.arduino.cc/arduino-motor-shield-rev3
"To avoid possible damage to the Arduino board on which the shield is mounted, we reccomend using an external power supply that provides a voltage between 7 and 12V. If your motor require more than 9V we recommend that you separate the power lines of the shield and the Arduino board on which the shield is mounted. This is possible by cutting the "Vin Connect" jumper placed on the back side of the shield. The absolute limit for the Vin at the screw terminals is 18V."
Pero bueno, si alguien quiere conectar su DCC++ a 50V allá él, igual hasta hace fuegos artificiales

Si, si, yo estoy de acuerdo contigo, El montaje oficial, puede que tenga esas limitaciones, pero en todas las webs que dan como límite 24 voltios (que la que he pegado no es la única), están hablando de clones.
