Are digital pins 5V (as std Arduino) or are the 3.3V?
I am thinking of interfacing with raspberry Pi GPIO and I probably need logic level shifter? :doh:
It’s 5V logic. With all the information about the microview, I am astonished that there is no mention of it’s logic level… I looked for over 10 min and finally found it by reading the comments from the Kickstarter page.
I am glad I didn’t buy one, as I find that there is a lot of info missing for doing real work with this device.
Yap that info was missing in microview “spec”…
I have found one lvl shifter and will try not to fry it or my raspberry
Here is the converter http://www.dx.com/p/mini-rs232-to-ttl-c … -5v-132934
:dance:
I recommend this one, https://www.sparkfun.com/products/12009
This one doesn’t have an IC that could get damaged just by touching it…
That is **not** a 3.3V to 5V level shifter. It's a logic level to **RS232** level shifter. The logic side levels can range from 3V to 5V. The other side will be RS232 levels (between +/- 5V and +/- 25V).povezi:

There’s a good chance that you will fry your Raspberry Pi if you try to use it with this converter!
The thing I like about these is that they also have a little voltage regulator for 3.3V so that you can power your 3.3V devices directly through this board.

There are several others as well… Not sure if Sparkfun has one with the built-in VR. But, It sure makes simple, low-current projects easy.
