Quote from: Bwinter on December 26, 2023, 10:26:07 AMSorry, but I'm not concerned AT ALL if the CPU is operating at 40C.  That is FAR below the recommended operating temperature.
That is not at all what I said.  'Not even close.  Please read my post again.  If you still have questions, please ask.
No more questions from me.  This board doesn't fit any of my needs/interests.

That is fine.  I don't expect everyone will want one, not even every FPP user.  However, for anyone interested in any one or more of the following:

  • Use a Raspberry Pi outside where the air temperature regularly exceeds 30C (85F)
  • Provide monitoring capabilities of power, fuses, etc. of the system
  • Mitigate or even eliminate failures due to loss of power, kernel panics, user errors, full storage media, etc.
  • Simplify powering and reduce cord clutter
  • Reduce the number of DC power supplies (and thus points of failure)
  • Run one or two pixel strings directly off the Raspberry Pi
  • Deliver 12-24VDC to an additional system (if the port is not needed for external cooling)

...these boards are worth a look.  Note a friend of mine produces a HAT whose only purpose is a battery backup for the Raspberry Pi.  He sells them on Amazon and ebay for around $65.  It's main advantages over these boards are it requires no external equipment and fits entirely inside the Raspberry Pi footprint, including the one or two 18650 batteries used to backup the Pi.  It is ONLY a battery backup and is limited to the capacity of two 18650 Lithium batteries, or about 25 Watt-hours.  There is no hard hypothetical limit for these boards, but using a readily available 7AH, 12V SLA battery, one can readily count on at least 80 Watt-hours.  If the Pi with attached 5V peripherals is drawing a nominal 2A, that is close to 2 days.
