Overview:
- Seamless power switching: automatic and instant switch from external power to battery backup with no perceptible delay.
- High-current USB-C input supports faster charging and higher current delivery compared with older micro USB interfaces.
- Suitable for uninterrupted power applications like routers, IP cameras, microcontroller boards and other low-power DC equipment.
- Energy-saving option: disable output indicator LED after testing to reduce standby current draw.
Usage Tips:
- Install a 18650 (or compatible 3.7V) cell in the battery holder before using UPS mode to ensure continuous output.
- If a large output capacitor slows transition to battery when input is removed, add a ~1K discharge resistor at the 5V input to speed switching.
- To increase run time, connect multiple batteries in parallel following safe battery-parallel procedures.
Safety Notes:
Use only compatible 18650 or 3.7V lithium cells with built-in protection or ensure external protection is provided. Observe correct polarity when connecting batteries and wiring to avoid damage or fire risk.
Charge and operate the module in a well-ventilated, dry area away from flammable materials. Do not expose the board to water or excessive moisture.
Avoid short circuits and do not modify or disassemble the module while powered. Use a proper USB-C power supply that meets the module's current and voltage requirements.
