Hi, just received this in the post, thanks. I was wondering if I need to do anything to get a 5V logic out on this card? I see there are a couple of solder pads marked 3.3V and 5V; do I need to bridge these to get 5V? If so, will 5V logic come from the output port marked 3.3V on the card? Also, do I need to do this in order to program an Arduino Mini/Nano or can I just connect the USB Adapter to the Arduino as it is?

Also, a pin diagram or notes on which pin of the USB Adapter to connect to which pin on the Arduino would be much appreciated..

(I did take a look in the other forums here, but couldn't find the HCARDU0011 referenced anywhere).

Thanks

John

Ok, spent a little time this evening and I've got it working fine, so I'm going to answer my own question in case it helps anyone else

First off, there was another topic about this in the , I didn't spot it It's in the Other Topics forum - http://forum.hobbycomponents.com/viewto ... =19&t=1495

So first off, I downloaded the driver from the link given, and plugged the controller into the USB on the PC, and set it up as a COM port.

A quick search on the web suggested that the 3.3V pin works at 5V as standard, so I assumed no solder bridge or jumper was needed.

Next, I connected to the USB Adapter to the Arduino Mini as follows:-

GND -> GND
VBUS -> 5V
TXD -> RXD
RXD -> TXD
DTR -> RESET (via a capacitor)

Once that was done, I loaded up Arduino blink sketch, and tried uploading to the Mini, but no joy. So I went into the COM port settings in Windows Device Manager, and set it to 9600,N,8,1 with Hardware flow control.

Result: All working nicely, the code gets uploaded to the Arduino Mini without me having to juggle the reset button like I used to have to do when programming the Mini from a Duo, so I am now a happy fellow

Hope the above is helpful to anyone who isn't 100% confident on how to use this adapter!
