Can the Dasduino Core board operate at 12V DC?
Original message (Croatian)
dali pločica DASDUINO CORE može raditi na 12 V dc ?
Originally submitted via email support on 13 April 2022. Migrated to the forum for community visibility.
Soldered Support:
The Dasduino Core board can accept a maximum of 5V on the VCC pin.

hvala Vam na upitu.
Nažalost, kod Dasduino CORE pločice može se dovesti maksimalno 5V na VCC pin.
Customer:
Is it possible to use a resistor to drop the voltage and achieve a lower voltage?

A dali je moguće da sa nekim otpornikom rušim struju pa time dobim pad napona?
Soldered Support:
You can step down the voltage to 5V using a resistive voltage divider with a combination of resistors, or more simply using a step-down module like Step-down modul s LM2596S – Soldered Electronics

hvala Vam na brzom odgovoru.
Napon možete spustiti otporničkim djelilom na 5V kombinacijom otpornika ili jednostavnije pomoću: Step-down modul s LM2596S – Soldered Electronics
Customer:
How much current does the board draw while operating, and what is the maximum current available on the output pins?
Original message (Croatian)
Koliko sam uređaj vuće mA dok radi i koliku max struju daje na izlaznim pinovima?
Soldered Support:
The board consumes approximately 30-40mA, though this can be higher depending on what program runs on the microcontroller. Power consumption can be reduced by putting the microcontroller into sleep mode. Given this current draw, powering the board through a resistive voltage divider would be difficult, so a step-down module is recommended instead. Each pin can provide 20mA of current. Of course, when you have loads connected to each pin, the overall board consumption increases accordingly.

Pločica troši oko 30-40mA, ali to može biti i više ovisno kakav program se vrti na mikrokontroleru. Svakako potrošnja se može i smanjiti ako se koristi mikrokontroler postavi u sleep. Zbog navedene struje teško će te pločicu napajati preko otporničkog djelila te bih Vam preporučio Step-down modul za koji je kolega [name removed] stavio link u prethodnoj poruci.
Što se pinova tiče svaki pin može dati 20mA struje. Naravno kada na svakom pinu imate neko trošilo raste i ukupno potrošnja pločice.
