A compact but high powered DC-DC step-up (boost) power supply converter module. It features a wide operating supply range with a power supply input voltage between 3 to 35V and will step-up this input voltage from 3.5V to 35V. The module also includes an integrated voltage meter that can measure both the input and output voltages. A voltage selection button allows for easy switching between the two. Together with its high multi-turn precision potentiometer this means any desired output voltage within its supply range can be sent without the need of an external test meter. Additionally LED indicators show power and input or output metering.
