Mini Uninterruptible Power Supply module, Supports charging And Power output at the same time, 5V 2.5A Output
We have ✅ 1 available of the WS-24760 in our Sydney warehouse. An extra 10 units available with a short lead time.
A compact uninterruptible power supply (UPS) module that supports simultaneous charging and power output. When external power is connected, it charges the batteries while providing a stable 5V output. If external power is lost, it automatically switches to battery power without interruption — keeping your system running.
The module communicates over I2C (via an onboard INA219), allowing real-time monitoring of battery voltage, current, power, and remaining capacity. It is designed for easy integration into mobile robots, embedded systems, and industrial control applications.
Key Features
- Uninterruptible Power – Seamless switchover between external and battery power
