Make sure that the atmega32u4 board is connected and powered.Ĭonnect the Leonardo arduino to the PC using the blue USB cable. CP2102) is connected and powered, and that the wiring with the atmega32u4 board is correct. Make sure that the USB to UART board (e.g.
Right-click on the arduino.inf file and click on Install. Download the Arduino Leonardo drivers and save them into the same folder: Second, the software, I will quote this part from the official Tutorial and make some comments.Ĭheap Arduino-compatible atmega32u4-based boards For the ground connection, I cut a peace of coaxial cable and used the females jumper cables (that came with the CP2102) to connect this terminal to the Arduino Leonardo. I followed this scheme to assemble the Arduino Leonardo with the CP2102 (Image borrowed from this forum):īecause I didn't consider in the beginning in ordering the female to male jumper cables, I connected the CP2102 directly to the Arduino Leonardo, matching RX>TX and TX>RX, because my board has these inverted (it is mentioned in the official tutorial). So, I won't explain the whole process, as there is already an official tutorial and other people have already posted their own tutorials for the teensy or Raspberry Pi, which are pretty much the same.īe aware that english is my second language, so if anyone sees some grammatical error, please let me know.įirst, eventually we have to follow the official guide:Īlso, these cables would help, but I didn't get them because I didn't know, anyway, it worked well for me with out them. However, the beginning was a bit confusing for me. Just want to do my contribution to this method, as it has worked amazing for me.
