VBUS 5V ( With cut on PCB)

Why cut 5V? Can you verify with a meter that 5V is coming out the USB type A connector? If not the USB device, it is not receiving any power.

Apply 5v to the USB output, the cut line is for operating on devices that cooperate with 3.3v supply, which there aren't many of those, typical use case is a self powered device, such as powered hub, or DSLR camera.

There is no need to connect reset, in fact, don't connect it at all. The chip is reset via software.

is your arduino 5V ? the shield should only be powered and communicate with 3.3V as you are saying you're using a nano, it would probably be the cause, and you might have fried your shield

i got a shield mini just like yours working with a nano, but trough a level shifter

Fizzi1470 commented 1 year ago

from the datasheet of the max chip : image

you are supplying 3V to the chip, which is whthin its limits, but then communicating at 5V, which is way too much for it

Hi,

I've seen other users saying this Chinese board doesn't work, I bought one and couldn't get it to work, years ago, when I have time I'll try again.

But I have the shield board for Arduino UNO which has two IC 74HC125 to convert 5V and 3.3V, this one works, I just don't remember why I put a jumper from the RESET button to pin 12 of the IC 74HC125 next to the IC MAX, the diagram already shows this connection, maybe my board was defective.
