| May 18, 2018 at 10:49 | comment | added | Shashi Kiran | @user2497- You mean provide Uno's 5V -> to 5V ( or 3.3 using the level shifter) of the PL2303 breakout board. Is the break out board not getting power from the USB port of my Mac. A really small red light lights up on the PL2303 when I plug in to my Mac USB Port. | |

| May 18, 2018 at 10:22 | comment | added | Shashi Kiran | @user2497 - Thanks, So I am not connecting the PL2303's 3v3 to the Arduino's 3.3v - Is that right. I tried about 3 of the Arduino's so far - and the "Uploading" stays put for a long time ! after I have clicked on the Reset Button of the Uno. ! On a side note - all the 3 Uno's boot-led- near pin 13 lights up when powered by a 5V USB. ( that is before I even try to upload the code ) | |
| May 18, 2018 at 9:46 | comment | added | user2497 | @ShashiKiran Just use the default, and select the right serial port. You press reset just before the upload? The timeout is normal if you don’t press reset in time. | |
| May 18, 2018 at 8:08 | comment | added | Shashi Kiran | I reset the Arduino button just when I clicked the Upload on the IDE, and it's just uploading .. or timeout with the stk_recv error ! | |
| May 18, 2018 at 8:04 | comment | added | Shashi Kiran | I did not connect the 3V3 of the PL2303 and left if open. What is the Tools-> Board and Tools-> Programmer to use on the IDE ? | |
| May 18, 2018 at 8:02 | comment | added | Shashi Kiran | PL2303 Tx -> Arduino Rx <br/> PL2303 Rx -> Arduino Tx <br/> PL2303 GND -> Arduino GND <br/> | |
| May 18, 2018 at 8:01 | comment | added | Shashi Kiran | I have a PL2303 ( I think it's similar to FTDI) and installed the driver and was able to see the driver on Arduino IDE. PL2303 . Arduino | |
| May 17, 2018 at 15:49 | comment | added | JRobert | Unos (real or cloned) use a 2nd processor on the board to manage USB communication with your computer. Since that processor or its firmware on your board is not working, @user2497 is suggesting you bypass it with another one on a breakout board or built into a cable. That breakout board or cable will almost certainly use an FTDI chip, regardless of what chip on the clone board has. You'd connect the breakout board or cable directly to the ATmega328p's RX and TX pins, just as its (now non-functional) 2nd processor is. | |
| May 17, 2018 at 14:35 | comment | added | Shashi Kiran | Thanks for the answer - I have a cloned Uno and a Nano. I guess I have to use a different breakout ? My Uno/Nano has a 340G chipset, not FTDI. | |
