Will These Parts Work?

Hey, everyone.

I'm new to all of this, having only discovered it today.

Would these parts work for building a USB Adapter? I'm trying to build this as inexpensively as possible.
1) Leik UNO R3 Board
2) Leik CP2102 USB to Serial Converter

Amazon does have some Teensy Boards, but none of them appear to have pins on them, and I want to build the version that doesn't require soldering. If this setup won't work, can you suggest some alternative parts, preferably from Amazon (I have gift cards)?

Thanks! :)

EDIT: Another thing I'd like to know is if I can use the 360 controller and the mouse at the same time? I do this with Battlefield 4 because I suck with the keyboard for gaming on account of limited mobility and flexibility in my left hand due to an accident when I was younger. I use the controller to move my player, aim down sights, do certain actions, etc. while the mouse is for looking around, firing, doing certain actions, etc.

Hi,

The Leik UNO R3 Board is not compatibile (ATmega328P).
I suggest you to look for an atmega32u4 board.

The CP2102 board should work fine.

You can use all your devices at the same time!

Are you sure that board won't work? If you look at the description it says something about using the ATmega16u2, which you can see on the board by clicking on the second picture, then hovering over it to enlarge it. The little chip next to the silver metal oval piece says MEGA16u2 on it. I don't know if that matters or not.

If it indeed isn't compatible, could you find and suggest one that would work on Amazon? :)

Oops, I did see the on board atmega16u2, which is compatible.
Just make sure to disable the UART of the atmega328p (or remove the chip).

Is that chip easily removed? I'm not handy with a soldering iron to be able to heat the solder and remove the chip if it's soldered on...

If it's not easily removed, is disabling the UART easy? I'm sorry to ask so many questions, but this is all new to me and I don't want to get the wrong parts or otherwise screw this up and waste money...

Thanks! :)

It is easy to remove the atmega328p chip since it is plugged in a socket.

Check the arduino documentation about reprogramming the atmega16u2:

Okay. So if I remove the chip I don't need to disable the UART, correct?

That board will work so long as I do one of the two; remove the chip or disable the UART?

I thought I made it clear, but again, yes, it should work as long as you remove the atmega328p chip.

But you'll also have to understand how to make the atmega16u2 chip boot into dfu mode. This involves either soldering a resistor as explained in the last link I posted, or following this instructions: link (you can use Atmel's flip programmer instead of the dfu-programmer tool).

If this looks difficult to you, consider buying a teensy 2.0 from the official store.

Okay. I'm sorry that I didn't fully understand what you said...

I may look into getting an actual Teensy instead of the other one so I don't have to do any messing around with disabling things, etc.
