What is it?

This is an ultra low-power power supply and battery charging module designed for ESP32, Arduino, and other microcontroller-based devices. It provides a stable 3.3V output and integrates a lithium-ion/lithium-polymer battery charger (up to 500 mA) with a high-efficiency buck-boost converter.

Why did I make it?

Many DIY and IoT projects run on batteries, but typical power solutions are inefficient and waste energy in standby mode. I needed a compact, energy-efficient module for my own projects — one that could deliver stable 3.3V and extend battery life without complex configuration. So I designed this module for developers who care about long-term performance and reliability.

What makes it special?

Ultra-low quiescent current: only ~17 μA in standby
Smart power path management: switch seamlessly between USB and battery
High-efficiency buck-boost converter based on TPS63802, provide effective battery life
Boost mode if Akku less then 3.3 volt (discharged)
Buck mode if Akku more then 3.3 volt (full charged to 4.2 volt)
Switch automatically and provide stable 3.3 volt and allow you to use akku more effectively and long time.
Built-in 1-cell Li-Ion/Li-Po charger
Compact size: only 3.3 × 1.2 cm
Current 1 A
Perfect for low-power sensors, remote IoT nodes, and wearable devices
