Bought an arduino pro mini the other day and it arrived today. I intended to stick wires in , not realising it didnt have USB conversion in place. So now I'm stuck :S .
I would love to buy the cables pre made but I live in the UK and the price for the cable is £26 after P&P and VAT. The breadboard on sparksfun is similar since I'm not in the US it is a whopping £10 just to get the cable shipped!
So I'm left to make it myself. Now over here , I had a look on ebay for the arduino converters and , unsurprisingly , they are not there. So looked for USB to TTL connectors , hoping to find something on that , woohoo , found something! Mainly Asian manufacturers but a few UK distributors.
Before I buy one though (I'm looking at something like this http://www.ebay.co.uk/itm/USB-2-0-TTL-UART-6PIN-CP2102-Module-Serial-Connector-Converter-Adaptor-Cable-/290681214240?pt=UK_Computing_CablesConnectors_RL&hash=item43adf35520) I notice there are only 5 pins.
So my question is:
With these 5 pins , How do I connect those to the 6 on the arduino? Presumably one is duplicated?
Can't follow that guide to the word since the cable he is talking about isn't in any UK ebay shops. But I DO notice the cable has 5 outputs to the connection to the arduino.
I do see on the pin diagram on the ebay product , some of the outs match up with holes on the arduino where the 6 pin connector would go.
Thanks in Advance :)
EDIT: I meant £10 for the shipping alone , daylight robbery I tell you! But I can get an interface like we are talking about here shipped to the UK free?
