Arduino Leonardo based setup?

[aejan]

Good day / evening to everyone here.

im interested to build one of the diy usb adapter.

the only available here is Arduino Leonardo for the chip. the usb to tll is easy to get.

anyone got success using the leonardo board? if yes. please do post some pictures.

and also leonardo have micro usb.

The wiring is exactly the same as the teensy:



Rx and tx pins are on the top right:

So I happen to have a compatible USB -> Serial converter as well as an Arduino Leonardo.
Is there anything I can do to get things up and running with these two?

@OneDegree
I merged your topic there as it's the same question.

As explained on the wiki, you need a USB dev board (such as the Arduino Leonardo) and a USB to serial converter.

I am also willing to build my DIY adapter, but teensy isn't avaliable in my country, only arduino is. The Arduino Leonardo doesn't have pins, but I have also found Nano 3.0. It has ATmega328

Is it going to work with

Thanks.

The atmega328 is NOT listed as compatible.

It's possible to use male to female jumper wires.

I'll buy leonardo then.

How to load the firmware to leonardo? Installed the drivers in windows that came with arduino, but the FLIP could not open the usb device. Holding down the reset button does not help. Any tips?

I need to go into DFU mode, right? I just don't know how.

Okay it seems to work fine. The easiest way to load the hex file is Arduino Uploader

DFU is not needed.
