Re: Pi Zero W performance limiting torrent download speed?

Yes Pi Zero W is very slow, for the same price you can get the 3 model A+ a bit larger but way more powerfull.

Re: Faisabilité: plusieurs appareils photo sur 1 seul rapsberry?

Vu le prix d'une PI Zero ou même prix le 3 model A+ (que je recommande chaudement pour le rapport puissance prix) C'est mieux de faire *Une PI par caméra* afin d'utiliser des caméras Raspberry PI qui coutent rien.

Re: puissance par gpio

D’expérience seul le 5V (et plus) détruit immédiatement la GPIO. Le 3.3V et la masse aucun soucis : la source de courant du SoC fait parfaitement son boulot. Au point d'alimenter des petits leds 5mm directement sans résistance sans jamais avoir eu de soucis. Bien entendu je ne recommande pas de test...

Une mise à jours facilement installable (apt update / upgrade) met à jours les deux eeprom de la PI4 et on gagne pas mal en température.
Par contre j'ai été obligé de rollback une des deux eeprom (le VL805 de l'USB) pour contourner un problème de compatiblité niveau capture vidéo USB.
