I want to exchange some date between arduino and beaglebone, as far as I know, most arduinos works with 5v levels, so I need to convert 5v into 3.3v beaglebone in order to communicate with it.
Unfortunatly I have no pro mini 3.3v now, only 5v arduinos.
So I need to convert levels.
I have several questions.
I have UART TTL CP2102 converter, I am using it to programm my Arduino pro mini, can I use it directly with beagle bone without converter ? http://ecx.images-amazon.com/images/I/410n8%2BHhdNL.SY300.jpg like this.
I can buy this cable with pl2303 inside http://i01.i.aliimg.com/wsphoto/v0/32250361345/Free-postage-1pcs-PL2303-PL2303HX-USB-to-UART-TTL-Cable-module-4p-4-pin-RS232-Converter.jpg
Is it possible to power my arduino pro mini 5v with 3.3v supply and use it directly with beaglebone
- Can you provide simple level converter schematic to solder it quickly
All in all I need just to communicate with beaglebone via uart from pc with USB-UART converter or from arduino it doesn't matter, just to communicate and send some data.
Please suggest what is the best way to follow.
