Several sub-models available (w/case, w/o case, VGA, HDMI etc.
I understand at one time they planned to offer a capacitive model too but that fell thru.
The fully cased version is the heart of our CarPC build. Not too bad from a viewing or responsiveness aspects. A bit of a pain if you want to use HDMI cabling vs a VGA cable due to issues getting the native resolution of 800X480 to work.
I believe most of the models sold by those guys support reverse cam auto switch. Haven't got around to testing that feature though.
Pretty sure you just need a non polarized cap, .33 is a small ceramic cap classified as a bi-polar (can go either way) Hope this helps SNO
I talked to Digikey support and they said that they would use a polorized one and thats what it called for in the datasheet. however I am seeing the + for the 47uf one and not the .33uf one, which leads me to believe that its in fact a ceramic non polarized one like you say. I have read that you can replace a polarized with a non polarized but not vice versa. The person at Digikey said its just for smoothing out current flow so they would use the polarized one. I dont know that much about integrated circuits, chips, capacitors and resistors so if this support person says thats what they would use I guess thats what i should go with right? On the other hand, i dont want to burn down my car because of a $0.20 capacitor.... What do you think?
Well all my .33uF's are non polarized and have been using them for the same purpose for a few years and have not had a problem. I think it's like this, they are for smoothing only and going in the regulator is really regulating the automotive varying voltage the output I would use the polarized cap as it is smoothing out the output voltage and thats where I would want the real smoothing taking place. The 47uF is an electrolite cap and the .33uF is a ceramic. Thats what I do SNO
