Customer:
The Croduino Nova2 board I purchased is defective. The 5V output only provides 4V, which is not sufficient for my projects.
pločica Nova2 kupljena kod Vas prije par dana je neispravna. Na izlazu 5V daje svega 4V što nije dovoljno za projekte za koju sam ju kupio.

Soldered Support:
The voltage on the 5V pin is the USB voltage minus the voltage drop across a diode of approximately 0.7V, which is part of the auto voltage select circuit. If USB is around 4.7V, you will find 4.0V on the 5V pin. This is normal behavior for the board.
napon na 5V pinu je USB napon - napon diode oko 0.7V, kroz koju prolazi (auto voltage select circuit). Ako je USB oko 4.7V, na 5V ćete pronaći 4.0V.
Nažalost, to je ponašanje pločice i tu ne možemo puno. Ukoliko Vam proizvod ne odgovara, uvijek ga možete vratiti i dobiti Vaš novac natrag: Soldered: Open-Source Electronics, Boards, Sensors & Modules – Soldered Electronics
