For those of you who have worked with the Petit Crouton before, I have a question. If I want to run the board with a white Seoul P4 and no accent LEDs, do I need 3.6V or 7.2V to power it? Also, did I hear correctly that the sound bank on the Petit can now be customized with your own sounds rather than being restricted to only the Light and Dark Meat fonts? Thanks a lot!!!
