Frequently asked questions

How do you change the operating mode on the picoPower Board?

Press the button below the device; the LED lights while the key is pressed and turns off when released, indicating the selected mode.

What voltage can be used to power the AT32UC3L064 on the board?

The AT32UC3L064 can be powered by either 3.3 V or 1.8 V, depending on the mode of operation.

When should the 7.8 V jumper be set?

The 7.8 V jumper must only be set if the 1.8 V power supply is connected; otherwise it must remain open.
