Topic: UART to USB converter question (Read 605 times) previous topic - next topic

Hey there,

i've just got a little question about UART to USB converters.
I would like to read out a GPS receiver from "u-blox". The receiver has got a USB cable to communicate with.
It also gets its voltage supply via the USB cable. Reading the receiver via a Laptop is not an issue at all but now i need to read the data via
the arduino.

This is a converter I'am thinking about to buy:

My question is:

Does it matter from which side (USB or UART) the supply voltage is going on to a converter?
I'll have to supply the voltage from the arduino so that the GPS receiver gets its voltage via the USB side.

I hope you guys are able to understand my question because my english used to be better =)
Thanks for replies!



Your GPS is a USB client device. A UART/USB adaptor is also a USB client device. Client devices can't be connected together. You'll need a USB host shield on your Arduino.

Hey there,

thanks for the quick response.
Do you have any good tutorials for setting up a usb connection via the USB Host Shield?
I just need to receive the bytes from the GPS reveiver and foward it to the Bluetooth module via the Arduino.
That shouldn't get me any issues right?



It would depend on the type of device that your GPS presented itself as. Circuits@Home support some GPS devices on their host shield - http://www.circuitsathome.com/products-page/arduino-shields/usb-host-shield-2-0-for-arduino/.
