Modifying the LJTick-LVDigitalIO for 5V
This is a short tutorial for how to modify a LJTick-LVDigitalIO accessory to change the 1.8V option to 5V. Larger versions of each image are linked and can be downloaded at the bottom of the page.
On the bottom side of the tick, locate the 1.8V regulator chip (U3) and the un-populated R5 resistor pad.

Remove the 1.8V regulator chip (U3) located on the bottom side of the tick.

Add a 0 ohm resistor or a jumper wire.

Optionally re-label the 1.8V selection to say 5.0V.
