Mini DC-DC Step-Up Boost Converter Module — 0.9V to 3.3V / 5V, 500mA (2-Pack)
This mini step-up boost converter converts a low input voltage as low as 0.9V up to a stable 3.3V or 5V output at up to 500mA. It enables powering Arduino, ESP8266, and other 3.3V/5V microcontrollers directly from a single AA or AAA battery, a partially discharged LiPo cell, or any low-voltage DC source. Supplied as a 2-pack for prototyping convenience.
