MiniBoost Development Tool Adafruit MiniBoost Development Tool is perfect for use with battery-powered projects with 2 or 3 Alkaline or a single Lithium battery. This booster uses a charge-pump topology that makes it compact and cost-effective. The charge-pumps double the incoming voltage, then regulate down, making them ideal for low current applications. The MiniBoost development board delivers up to 5V voltage and 100mA current. This tiny board comes in a small 15mm x 10mm x 3mm / 0.6' x 0.4' x 0.1' form factor.
