Low profile 1A DC-DC boost converter

This little module measures around 22mm long x 11mm wide and just 4.5mm thick. It has a selectable output voltage of 5V, 8V, 9V or 12V, and the input voltage must be lower than output voltage.

Output voltage is selected by bridging the solder points marked A and B. It comes with both points bridged by default, for a 12V output. For other voltages, remove the zero-ohm resistors at the appropriate points A and B, as per the table on the back of the board and below.

Voltage	A	B
5V	Unlinked	Unlinked
8V	Unlinked	Linked
9V	Linked	Unlinked
12V	Linked	Linked

Rated output currents are:
1A @ 5V
0.7A @ 8 or 9V
0.5A @ 12V
Do not exceed rated output current!
