In the manual, the following is mentioned about the VIN pin:

The VIN pin on the ShieldBuddy power connector strip allows access to the 9-12V input from the power jack socket. This may be used to power shields that require a higher voltage e.g. the DC motor shield.

I saw numerous posts where the administrator is using 9V.

Is 12V safe? I tried 12V but the bottom of the ShieldBuddy becomes very hot .....

What is the community's experience? I would really prefer to use 12V as more adapters are available ..

Thanks in advance.

The latest ShieldBuddy "4269.03.06210_B1" can run with a 9V supply but if there are shields fitted that consume a lot of current then it will get very hot. 12V is too high. Although the regulator can cope with it electrically, there is not enough heat dissipation for long term use. You could fit a small heatsink to the regulator.
