Im planning on putting an arduino in a space below my radio in my car, im just wondering if there are any precautions I should take and if the ones im planning are neccary
here's my planned ones
5v regulator to keep about 200 ma draw off the board
Adj regulator to smooth the 12/16 volt input to like 9/10, worried about how serious it is to go above the 12 volt recommended input
100uf cap to smooth vin
12v dc fan to circulate air, im. Ot sure how neccesary this is but I heard a car can get to like 160 degrees f and I don't wanna destroy my tft screen
is there anythiing else I should be worried about?
Sounds like a good start.
How will you keep the wires secured to the board?
if you can afford a $4 regulator, take a look at this: http://www.mouser.com/ProductDetail/Murata-Power-Solutions/OKI-78SR-5-15-W36-C/?qs=sGAEpiMZZMtwaiKVUtQsNemMZL4TplJBqOl7845nWHA%3D
should reduce heat substantially by regulating the 12-14.5VDC car voltage directly to 5V with a switching-type power supply.
Im using female to male jumper wires I got off ebay, they make it real easy to move things around
especially since this project requires 28 different connections to my arduino mega
And so far ive had no problems with them
And that seems like an interested power supply, ive didnt know they made them that small
yeah I think CrossRoads or someone else posted it in another thread, I looked for some others by that same brand... it was precisely what I was looking for with a future car project. probably going to use one of these in the near future: http://www.mouser.com/ProductDetail/Murata-Power-Solutions/NEF0100501B0C/?qs=sGAEpiMZZMtwaiKVUtQsNRzjbVtspr5i0nwnBWiI%252bn8%3D
not too bad, $20 and it basically absolves me of having to think through fancy heat dissipation/power regulation problems!
Yep I did, Retrolefty first pointed them out tho, so I can't take full credit.
I had been recommending these form Pololu for a few dollars more, had good results with them in my projects; both 5V stepdown (from 12V), and a 12V boost (from 5V).
