hELLO EVERYONE, I am using ZEDF9P RTK2 of Sparkfun with Arduino Uno. I tried to program it via UART but it is not giving any signals on u-center however with USB to TTL it is giving. Can anyone help me how to receive signals with this board via UART on Arduino Uno?
What did you program, your Arduino or the GPS?
Is there any reason why you’re not using I2C? (Qwiic)
I dont know how to connect via I2C. I have studied but still don’t know how to make a connection of ZED in the case of I2C with Arduino. Kindly tell me for both I2C and UART.
Again, are you trying to program your Arduino or the GPS with the Arduino IDE software?
Sparkfun has a nice guide on how to hook things up, you might check that.

You’re probably better off using a qwiic cable [like this one and connecting the wires like so to your Arduino:
Red - 3.3 volts
Black - Ground
Yellow - SCL
Blue - SDA
If you do that, the examples in the library will work for you.
What are you using for an antenna?](https://www.sparkfun.com/products/14425)
Yes i am tring to program GPS with the help of arduino by arduino IDE software. I am trying to enable GLONASS on ZED with the help of arduino. I will write my configuration commands on it. But i get to know that this board is lacking level shifters and I am using Arduino UNO which can damage it. What is your opinion in this?
I am using multiband antenna mainly L2 L2.
My advice would be to stick to Sparkfuns directions and use the qwiic cable linked below. As long as you don’t have other I2C devices connected to the arduino that use 5 volt I/O, you should be fine without any level shifting. Just make sure you connect the qwiic cable to 3.3 volts and not 5 volts.
If I use level shifter can I do that? I dont have QWIIC cable and it will take time in shipping so i need to do that by UART.
