Micropowercore Charger + 3.3V Buck-Boost Power Module for ESP32 & Arduino, Iq 17 μA

DC-DC boost/buck with stable 3.3V + charger from USB (LiPo,Li-Ion, 1 cell). Ultra-low quiescent (17 μA), current up to 1A

 

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.

Battery-powered DIY and IoT projects demand more than standard power solutions, which often waste energy in standby. Micropowercore was created to solve this challenge — a compact, ultra-efficient module that ensures a stable 3.3V output and significantly extends battery life. Designed for makers and developers, it combines long-term reliability with effortless integration into any project.

Key features

Battery management

The BQ24xxx IC manages the charging process for single-cell LiPo batteries. With built-in safety features, it prevents overcharging and extends the battery’s lifespan. The charging process is monitored via onboard LEDs that indicate charging progress and completion.

Buck-Boost conversion

The TPS63xxx ensures a stable 3.3V output, regardless of the battery’s charge state. Whether the input voltage is higher or lower than the required output, the converter adjusts efficiently to provide consistent power to connected microcontrollers and sensors.
