Powering the Chumby Hacker Board

Power jack

The Hackerboard requires a regulated 5VDC power supply, positive tip, via a 3.5mm OD, 1.4mm ID barrel jack (sometimes referred to as a 3.8mm or 4mm connector). To connect you will need a matching plug, such as this. We suggest a regulated switching supply with over 1000mA output capability. The power required by the board itself is not that high (100mA? check this) but if you plug in a Wifi dongle into the USB port, or an LCD into the LCD expansion port, the power required can easy climb to a 1000 mA. Since the connector is the same as those used in the PSP, you can use PSP power supplies and chargers!

Under no circumstances should you power the device with anything higher than 5V, you will destroy it!

Lithium battery

Needs factchecking

The board can also use a lithium ion/polymer battery for power. The board even has a built-in lipoly charger! (is it activated by default? what charge rate?)

If powering from a lipoly, the chip will boost it to 5V to supply power to one of the USB port s(the top one, on the same side as the power jack) but not to the other two.
