Soldered Support:
You’ll need to provide a screenshot of the COM ports from Device Manager so we can check if it’s a driver issue.
You can try two things:
- Tools - Boards - Arduino Nano
- When you press “upload” in Arduino IDE, press the button on the Croduino board. When uploading appears, release the button.
Please send us feedback on which LEDs light up when uploading appears, both with and without the button trick.

trebali bi screenshot COM portova “Device managera” kako bi mogli provjeriti je li do drivera.
Možeš probati dvije stvari:
1.Tools - Boards - Arduino Nano
2.Kada u Arduino IDE stisneš “upload” pritisni tipkalo na Croduino pločici. Kada se pojavi uploading pusti tipkalo.
Molim te pošalji nam feedback te koje ledice zasvjetle kada se pojavi uploading s i bez trika s tipkalom.

I tried both tricks and it gives me the “notsynced” error, just with a different number at the end.

probao sam oba trika, izbaci mi “isti error”, notsynced, samo druga sifra na kraju..
Customer:
The LEDs stay on the same the whole time. The blue and yellow ones - the yellow one is the blink test.

a ledice stalno svijetle iste 
da sad ne trazim kako se zovu, plava i zuta za koju i jest blink test
Soldered Support:
The drivers look fine, so the next assumption is that the ATmega may be corrupted. Can you send the board along with your receipt to Soldered?

izgleda sve uredu s driverima sljedeća pretpostavka je kako je “spržena” atmega. Možeš li pločicu poslati, zajedno s računom, na :

The board is actually fine - I checked it. The problem is in the system. It doesn’t work on 6 devices with Windows 8, 8.1, and 10. On two devices with Windows 7 it works without issues.

Hvala na odgovoru, ali plocicu sam dobio od fakulteta, Banja [name removed] College, koji su plocicu dobili od vas. Uglavnom, plocica je uredu, provjerio sam, problem je u sistemu. Na 6 uredjaja sa win8, win8.1 i win 10 ne radi. Na dva uredjaja sa win7 radi bez problema
