I’m building a small chartplotter project powered by a raspberry pi. The whole system has:
– RaspPI3 (5V 3A)
– Powered USB hub from hard drive and few sensors (5V 2.5A)
– Screen (12V 1A)
All this will be hooked to the boat 12V batteries. I’m looking for a way to hook everything to the 12V system and monitor the power consumption of my setup. I’m getting a bit lost with all the different products (would something like this work? https://www.amazon.ca/dp/B00S7YK8KS?psc=1)? I’m not even sure There’s a way to monitor everything since I need both 12V and 5V? Any help would be much appreciated!
Hello Sam,
Thank you for writing in.
The item(B00S7YK8KS) you mention is a buck converter, it can’t monitor the power consumption.
Do you mean you needa a device that can monitor 12 V and 5V respectively?
Best regards.
Well, ideally I would like something that can monitor both. But the first thing I need to look for is a step down for the PI and the USB hub that would make sure the voltage delivered (5V, total of 5 amp) is stable. Being able to monitor the power consomption is optional..
Forgot to add: I’m looking for something as efficient as possible for the step down to conserve battery and since it will be in the tropics, it needs to stay cool pretty easily…
Hello Sam,
Thanks for your reply.
If you want to step down voltage from 12v to 5V, the item(091013) you mention previously should be suitable. But it has better use it within 4.5A.
Best regards.
Could you suggest me a step down best suited for my need? I need something that is extremely stable and efficient and able to either deliver 5V @ 6A or 5V@2A (I would then buy 2). If there’s a power consumption monitor that I could put before this step down, I would be interested in knowing about it. Thanks a lot
