While pis are used in more and more aspects, it gets critical to ensure power supply. A normal USV / UPS (unterbrechungsfreie Stromversorgung / uninterruptible power supply) is fine, but a spcial USV for the PI has some benefits:
– propper shutdown
– power supply monitoring to check the supply (batterie only, no batteries given, etc.)
The USV / UPS will be attached via the „normal“ micro USB
It will send signals like BATLOW, BATPOW, PIREADY via GPIO.
Even without using the GPIO ports, three LEDs are indicating the status of the USV.
Cw2. is based in Germany
Costs? 29,99 €.
