Extra USB and Battery Backup
#1
Just saw this on Banggood. It might be helpful for those who are looking for battery backup and a few extra powered USB ports.

Looks good !
I like
  • the idea to attach that board at bottom, and not at top, of the raspberry ;
  • the presence of one powered usb HUB 4 ports ;
  • all required H/W included in delivery
  • the presence of one on/off switch
I wonder weither :
  • the SD card is protected in case of 5v supply failure ?
    (probably no as not mentioned and no access to GPIO)
  • the 2.0 A output power is sufficient to drive the raspberry, its HATs and the provided  hub + connected peripherals ?

Just reading up on this - they don't recommend charging the battery while the PI is running, and they don't provide a signal if the battery is running low, so out of the box it wouldn't be possible to clean shut-down the PI. Something like that could probably be implemented by using a GPIO and detecting voltage on the board, I would think. The questions and answers on Amazon.com are very interesting.

Too bad - this looked very promising. It's frustrating that they would do so much yet leave out something like UPS capability.

On Amazon.fr the price is  more than double : 10.35€ on banggod compare to 20.88€ on Amazon.fr !!!
