First, sorry for the probable bad english, it’s not my native language.
I’m having trouble deciding what to do for my setup:
– I wanted to buy an OSPI board. Since the board will be standalone, I thought that a RPI 1 B+ would be more than enough. Thing is, those are amazingly hard to find in France, and are right now more expensive than RPI 3
– If I’m going for a RPI 3 + OSPI setup, will a 24V AC (240V input) will be enough to power the cards ? I’ve read that some are having trouble with this setup
– Considering all of the above, I’m starting to wonder if I should go with an AC OpenSprinkler controller (no Pi)… I guess it has more reliability, but lacks the power of RPI possibilities when it comes to programming extensions ?
My main concern is with the rather large current consumption of RPi 3. OSPi was originally designed to output only 500mA at 5V voltage, and now increased to 1amp. But RPi 3 seems to require a much higher peak current. Some users have reported success using RPi 3, but I would personally recommend RPi 2 A+, B+, or RPi zero. I understand the build-in WiFi on RPi 3 is desirable, but I am concerned that even our next batch of OSPi (which is designed to output 1.5amp @ 5V) may not completely meet the spec of RPi 3.
