MBED Power Supply
Hello
is it safe to use a 12V adaptor rated for 1 amp to power the MBED? does it overheat the MBED?

You cant have too much ampere from an adapter, and 1A is more than enough, so that isnt the issue. However the mbed is rated at 9V input voltage max. Does it survive 12V? Yes, however it depends on how much current the mbed draws and how much is drawn from your 3.3V output of the mbed. The problem is simply power dissipated on the voltage regulators. If you consume alot of power, they will become too hot with 12V.
