Customer:
I need to know the voltage on the digital and analog pins of the Dasduino CORE and LITE, but I cannot find this information. Both boards state a 5V operating voltage, but the images only show 3.3V. The presence of a Li-Ion battery charger suggests 3.3V, but I’m not certain. There is a VCC pin, but I cannot determine the allowable input voltage range from that alone.

Zanima me za Dasduino CORE i LITE koji je napon digitalnih i analognih pinova jer taj podatak ne mogu naći. Za obje pločice piše da je radni napon 5V, ali na slikama ima samo 3,3V. Kako imaju punjač za Li-Io bateriju to me navodi na 3,3V ali nisam siguran. Ima VCC pin ali ni iz toga ne mogu zaključiti koji je dozvoljeni raspon ulaznog napona.
Zahvaljujem, unaprijed.

Dasduino CORE is powered by 5V, which is the voltage on the VCC pin. When powered via USB, this is approximately 4.8-5V. When powered by battery, the VCC pin carries the battery voltage. Therefore, the voltage on all pins is VCC, which depends on the power source. With external power, you can power the board through the VCC pin. With USB, you can use VCC as a 5V output for a sensor.
Dasduino LITE is different and is powered by 3.3V, so its pins will have a maximum of 3.3V. You must be careful not to connect a signal with a higher voltage level to the analog or input pins.

Kroz koji mjesec bit će spremne i datoteke za Dasduino LITE te će onda i one biti dostupne na našem GitHubu.
Dasduino CORE se napaja s 5V odnosno s naponom koji je na VCC pinu. Ako se napaja putem USB-a onda tu bude oko 4.8-5V. Ako se pločica napaja baterijom onda je na VCC pinu napon baterije. Prema tome napon na svim pinovima je VCC što ovisi o izvoru napona. Ako imate vanjsko napajanje pločicu možete napajati putem VCC pina, ako pak koristite USB onda VCC možete koristiti kao 5V izlaz za neki senzor.
Dasduino LITE je nešto drugačiji i on se napaja s 3.3V tako da će na njegovim pinovima biti maksimalno 3.3V. Zbog toga treba paziti da se na analogne ili ulazne pinove ne spoji signal koji ima veću naponsku razinu.
Ako je potrebno još nešto pojasniti slobodno pitajte.
Soldered Support:
The maximum input voltage for all Dasduino boards is 5V on the USB or VCC pin. The VCC pin connects to a regulator that converts 5V to 3.3V. The microcontroller pins carry the supply voltage of the microcontroller itself (either 5V or 3.3V depending on the supply voltage).
For Dasduino CORE: if you supply 3.3V to the VCC pin, it will operate at 3.3V but the 3V3 pin will have a slightly lower voltage because it goes through the regulator. It is best to power it with 5V on USB or the VCC pin.
For Dasduino LITE: the operating voltage is 5V, meaning you can connect 5V to the VCC pin, and the regulator will step down that voltage to 3.3V.
You can supply 5V to the VCC pin and the board will work because it has a regulator on board that will adjust the voltage for the microcontroller if needed.

Za sve Dasduino pločice ulazni napon je max 5V ( na USB ili VCC pin). S VCC pina ide na regulator koji 5V pretvara na 3.3V. Nekada prije na Croduino pločicama je bio dodatni regulator za veće napone ali to smo izbacili te dodali neke druge stvari.
Ovisno o mikrokontroleru neki se napajaju s 5V neki zahtijevaju napajanje od 3.3V. Mikrokontroler na svojim pinovima može imati napon napajanja istog (znači ili 5V ili 3.3V ovisno s kojim naponom se napaja).
Ako kod Dasduino CORE pločice dovedete napajanje od 3.3V na VCC pin on će raditi na 3.3V samo će na 3V3 pinu biti nešto niži napon jer ide kroz regulator. Najbolje je napajati ga s 5V na USB ili VCC pin.
Za Dasduino LITE radni napon je 5V što znači da na njega možete spojiti 5V na VCC pin, a regulator će taj napon spustiti na 3.3V.
Na VCC pin se može dovesti napon od 5V i pločica će raditi jer se na pločici nalazi regulator koji će prilagoditi napon za mikrokontroler ako je potrebno.
