IAN CANADA UCPI 2025 Universal Ultracapacitor Power Supply Board for Raspberry Pi - reviews - There are 7 reviews.

Tout n'est pas parfait
Je pensais à tort que les supercondensateurs fonctionnaient en quelque sorte comme de petites batteries et stockaient de l'électricité pendant une certaine durée. Ce n'est malheureusement pas le cas. Sur mon Pi5, ils se chargent très rapidement, il n'est pas nécessaire d'attendre les 20 à 30 minutes indiquées dans le mode d'emploi pour que la LED 3 s'allume. Quelques secondes suffisent pour le processus de charge. Est-ce normal ?

Après tout, la carte permet d'alimenter le Pi5 avec une batterie externe normale.

Good value
I did a review of Ian Canada TransportPi and this was added to it. It subtly improved my overall perception of sound quality of that board. Not sure how it actually measures for noise, which is something I am interested in. But I do think the ability to run a device purely off an ultracapacitor to decouple from a direct mains supply is worthwhile.

Incredible good

Perfect for a PI streamer
No question, perfect for a Pi streamer with a good PSU

Agree with Clive S above: Ian knows his stuff
I had been having issues after a Roon infrastructure upgrade getting the same fantastic SQ I was used to on my main system. After trying a few RasPi digital transport hats that didn't do it, I reached out to Ian Canada via email for advice. He graciously responded the next day and suggested a transportPi Digi + this UCPi would solve my audio fidelity woes. Boy was he right! Got the TransportPi unit first and it was a huge improvement in the right direction. When the UCPi arrived 10 days later, wasted no time charging up the caps and installing. Bingo! This pairing along with upgraded clocks on the TransportPi does indeed deliver audio nirvana on a great system, it defies belief such bit perfect quality can be this affordable. Fun to play with the Pi units and wait for the next improvement to arrive, I just pretend I'm a 12 year old again waiting for the new parts of my nerd science kit to arrive! Thank you Ian Canada and Audiophonics.

Great product. I installed it under my raspberry pi. Installation was quick and easy I have a few speaker spikes keeping it off the table. I have a audioquest dragonfly red connected to the pi and what can I say. The bass has increased and it's tighter more accurate. The sound stage has widened everything just sounds better. Ian Canada sure knows his stuff.
