... but why the DC, Reset and CS pins wired to D3, D4, D5? Any particular reason?
Then I assume I can wire the pin 2 of the OLED(VBAT) to the 3V3 pin of the nano and all the ground connections to the ground of the nano.
I found this on Sparkfun but it has only 4 channels and I have 5 to connect. EDIT: I found this 8-bit bidirectional level shifter that seems perfect for me. Do you agree?
Hello olikraus!To the part "Then I assume I can wire the pin 2 of the OLED(VBAT) to the 3V3 pin of the nano and all the ground connections to the ground of the nano.", your answer meant I was right?
I think I will stay with the level shifter, as I can put it where I want with the screw holes, and the nano seems more common. If I understand right the functionment of the level shifter, I have to connect VA to the 5V output of the nano and the VB to the 3V3 output of the nano. Then every input on the level shifter on the A side will be converted into a 3V3 output on the B side? I obviously have to connect the GND pin to the ground of the nano, but what about the OE pin?EDIT: If it can help, here is a documentation about the level shifter used by this board: TXS0108E
-is the serial protocol different with a USB3 than with a USB2 port?
-can the nano be alimented only with the USB port (remember that I plan to aliment the OLED with the nano 3V3 output
I am not a specialist on this, but I guess regarding VA/VB you are right. OE probably means "output enable", but better lookup the datasheet.
hmm i am not sure, what you mean.
What do you me an by "OE should be high"? Do I have to connect it to some pin of the arduino?
This brings a question: how can I connect one pin of the arduino to multiple objects without a breadboard?
It requires 5V input and 50mA per led so 2A in common.
