Customer:

I ordered a Croduino Nova but after a few tests I have a problem connecting to my WiFi. The program uploads fine but after the Nova loses power or I do a reset it no longer connects to the WiFi network.

I also noticed some soldering errors on the CP2102 and around the reset button and I’m wondering if that might be the problem.

Kod vas sam naručio Croduino Novu ali nakon par proba imam problem kod spajanja na svoj wifi.kod uploada programa sve radi ali nakon što Nova ostane bez napajanja ili napravim reset više se ne spaja na wifi mrežu.

Primjetio sam i neke greške kod lemljenj na cp2102 i oko reset tipke pa me zanima da li je u tome možda problem.

Soldered Support:

The soldering is not the problem, but rather an issue with the first version of the PCB that you received. Please use a knife or scalpel to cut the trace shown in the attached image. After you cut the trace, everything will work as it should.

Original message (Croatian)

nije problem u lemljenju, nego u prvoj verziji PCB-a koja Vas je eto zatekla. Molim Vas da nožićem ili skalpelom prerežete ovaj vod sa slike u privitku.
Isprike na tome :slight_smile: Nakon što prerežete vod, sve će radit kako treba.
