Key Features:

✔ Ultra-Wide Input Range – 0.9V–5V → 5V output (supports nearly dead batteries!). ✔ USB-A Output – Directly powers/charges smartphones, Arduino, Raspberry Pi Zero, etc. (max 500mA). ✔ High Efficiency (Up to 96%) – Minimizes energy waste for battery-critical apps. ✔ Auto Start/Stop – Powers on at ~1V, stops at ~0.7V to protect batteries. ✔ Tiny Size (22×17mm) – Fits into tight spaces (e.g., battery holders, solar chargers). ✔ No Wiring Needed – Plug-and-play with USB-A male port (or solder pads for custom projects).

Applications:

• Emergency Phone Charger – Boost 1x AA/AAA/NiMH to 5V for USB devices.

• Solar-Powered Projects – Stabilize weak solar panel output (~2V) to 5V.

• DIY Battery Packs – Revive "dead" 1.5V/3V batteries (e.g., for LED lights).

• Low-Power Sensors – Power ESP8266/Arduino from a single cell.

Technical Specs:

• Input Voltage: 0.9V–5V (output shuts off if input <0.7V).

• Output: 5V (±0.1V) via USB-A or solder pads.

• Max Current: 500mA (sustained; peaks to 700mA).

• Quiescent Current: <100µA (minimal standby drain).

• Wiring Options:

  • USB-A plug (ready to use).

  • Solder pads (IN+/IN-, OUT+/OUT- for custom wiring).

Package Includes:

• 1x Boost Converter Module (0.9V–5V to 5V).

• Optional: Micro USB cable (specify if needed).
