can i use SBEC or switching voltage regulator it to power raspberry pi and arduino together , connecting with a 3s 2200mah lipo? does the electrical noise of sbec create problem for raspberry pi and arduino? i dont want 11v volt battery gets wasted by heat while conversion to 5 volt.
what options i have to power raspberry pi or arduino (5volt) from lipo battery? also does BEC coming from ESC is suitable for such charging?
:lightbulb: I actually was
:lightbulb: I actually was thinking of pairing the spider controller with my pi for servo control,
already have both - hadn’t thought of pulling power from the spider
Thanks a lot 
Thanks a lot
I use one of these
This is a little bit pricey compared to some others, but I use this to power the Pi + arduino via GPIO with pretty much any power supply, and it always gives a solid 5V. (6v NiMh, 7.4v rc lipo, 12v power supply, 12v car battery, etc)
