The power supply we send with the Lattice1 is a standard US 2-prong (type A) power supply.
Customers outside the US, Canada and Japan will have to use a plug adapter!
Input:100-240V 50/60 Hz 0.5A
Output: 12V 1.0A
If you want to move your Lattice1 and are worried about unplugging it, you can do so without any worries as long as there's not anything going on at the moment (e.g. a firmware update).
