This compact step-up (or boost) regulator generates 3.3 V from voltages as low as 0.8 V and delivers up to 200 mA, making it perfect for powering small 3.3 V electronics projects from one or two NiMH, NiCd, or alkaline cells.
This is a voltage regulator board. It has a terminal strip with a common ground, input, and Regulated output. Includes fuse, filter, and power LED. It uses a Dimension Engineering Switching Power 3A Supply for maximum efficiency and isolation.
