Romeo max Vin understanding
Account cancelled 2012-06-02 05:11:59 2612 Views1 Replies I need to run the Romeo with Vin 13-13.5 volts, which is close to the stated limit of 14 volts. I would like to know what drives the 14 volt limit so that I can understand the risk I am taking.
From a purely voltage perspective I do not see any components exposed to VIN that would have a problem with much greater than 14 volts, so I wonder why?
Can you please tell me briefly, but at an engineering level, what the issue is?
Thank you.

If you remove the Vin=M_Vin jumper you can actually supply somewhere arround 35V safely. the limit is arround 40V for the motor driver.
The reason we state that the limit is arround 14V is because of the voltage regulator for the Arduino. If you exceed this voltage you run the risk of damaging the voltage regulator for the Arduino. If the regulator pops, it is easily replaceable. You might even be able to source a more robust voltage regulator to suit your needs.
