Adafruit Powerboost 1000
The PowerBoost 1000 solves a big problem in portable projects – how to get ~5VDC from a battery. This breakout boosts voltages from as low as 1.8V to 5.2VDC meaning it can be used with AA batteries, LiPo, and other sources to power your 5VDC based project.
The 4A internal switch means you can get 1000mA+ from as low as 1.8V, 1500mA+ from 2 NiMH or Alkaline batteries, and at least 2000mA from a 3.7V LiPoly/LiIon battery or 3 NiMH/Alkalines
- 90%+ operating efficiency
- 1000mA from as low as 1.8V
- Full breakout for battery in, control pins and power out
- Perfect for many 5V powered projects!
