Customer:
How do I connect the Croduino Nova to a battery or power adapter? Also, if I connect the Nova to a Croduino Basic via serial connection (TX, RX), do I need to use a voltage divider since Nova runs at 3V and Basic runs at 5V?

molio bi Vas ako mi možete dati upute za Croduino Novu, odnosno kako da spojim Novu na bateriju ili adapter? Također pitanje, ako spajam preko serijske konekcije Novu sa Croduino Basic (tx, rx), pretpostavljam da moram preko djelitelja napona jer nova radi na 3V a Basic na 5V?

Soldered Support:
To connect Nova to a battery or adapter: connect the + pin to pin 5V and the - pin to GND. The 5V pin is actually VIN, but when you connect a power source to this pin, do not simultaneously connect the USB connector to your computer, since USB also supplies 5V to the 5V pin. The voltage on this pin should not exceed 5V, but you can safely go up to 9V.
For serial connection, yes, you need a voltage divider, voltage translator, or logic level translator (for example: Soldered: Open-Source Electronics, Boards, Sensors & Modules – Soldered Electronics).

NOVU na bateriju / adapter možete spojiti tako da na pin 5V spojite + pin, a na gnd spojite - pin napajanja/adaptera/baterije. 5V pin je zapravo VIN, ali ne smijete u trenutku kada spojite na taj pin nekakav izvor napajanja različit od 5V spajati USB konektor na računalo, jer je s USB konektora također povezano njegovih 5V na 5V pin. Ne znam s kolikim naponom biste išli na taj pin, najbolje bi bilo da ne prelazite 5V, ali do 9V možete sigurno.
Što se tiče serijske konekcije, da, trebate djelitelj napona / voltage translator / logic level translator. Npr: Soldered: Open-Source Electronics, Boards, Sensors & Modules – Soldered Electronics
