Upgrade your Arduino projects with the compact and reliable 5pcs DC-DC 0.9‑3.3V to 3.3V / 0.9‑5V to 5V Mini Step‑Up Boost Power Module. Designed for hobbyists and professionals alike, this voltage converter delivers a steady 500 mA output, ensuring your micro‑controllers, sensors, and modules receive clean, consistent power.
Key Highlights
- Wide input range: 0.9 V – 3.3 V (step‑up to 3.3 V) and 0.9 V – 5 V (step‑up to 5 V)
- Stable 500 mA output current for reliable performance
- Ultra‑compact footprint – perfect for tight spaces on prototype boards
- Low quiescent current and high efficiency (up to 92 %) to extend battery life
- Built‑in over‑current and short‑circuit protection for added safety
- Fully compatible with Arduino, ESP8266, ESP32, Raspberry Pi Pico and other 3.3 V/5 V platforms
- Pack of 5 modules – ideal for multi‑project kits or bulk purchases
Why Choose This Mini Boost Converter?
Many low‑voltage batteries (CR2032, Li‑Ion cells, or 2× AA) cannot directly power 3.3 V or 5 V boards. This module steps up the voltage efficiently, eliminating the need for bulky external regulators. Its tiny size (≈ 15 mm × 10 mm) lets you mount it directly on a breadboard or solder it onto a custom PCB without sacrificing board real‑estate.
Technical Specifications
- Input Voltage: 0.9 V – 3.3 V (for 3.3 V output) / 0.9 V – 5 V (for 5 V output)
- Output Voltage: Fixed 3.3 V or 5 V (selectable by module version)
- Output Current: 500 mA (continuous)
- Efficiency: Up to 92 % (typical)
- Operating Temperature: -40 °C to 85 °C
- Dimensions: 15 mm × 10 mm × 3 mm
- Pin Layout: VIN, GND, VOUT (standard 2.54 mm header)
Easy Integration
Simply connect the VIN and GND pins to your power source, and the VOUT pin to your Arduino or other 3.3 V/5 V device. No additional components or configuration are required—plug‑and‑play power conversion in seconds.
Ideal Applications
- Portable Arduino or ESP‑based IoT devices
- Battery‑powered sensor nodes and wearables
- Robotics projects needing stable voltage rails
- DIY electronics kits and educational labs
- Prototype boards where space is at a premium
Boost your project’s reliability and performance with the 5pcs DC‑DC 0.9‑3.3V to 3.3V / 0.9‑5V to 5V Mini Step‑Up Boost Power Module—the smart, space‑saving solution for all your voltage conversion needs.
