BOB-09370: This is a breakout board for our non-isolated, 6A DC-to-DC Converter Module. The module can convert any DC voltage between 4.5-14VDC to a selectable voltage between 0.59 and 5.5VDC. To set the output voltage to the desired level, a resistor must be added between the Trim and GND pins. For example, to set the module to output 5V use a 1.34kÎ resistor, or to get 3.3V use a 2.182kÎ. See table 1 in the module's datasheet for more resistor values.
