Second, about current flowing I’m not sure if the traces have enough widght to hold the current. (Something doens’t look well to me but I can’t figure it up what is it). I tried to make the GND connections ootside the Nano Iitself (maybe im lacking on basic electronic theory, thinking to avoid high current passing through the Nano).įirst, I’ll like to know if you, experts, can help me out with this design and identify the possible problems. Somehow, I got a mess on the PCB and now I’m Kinda lost. I’m attaching 2 fritzing projects, one of them is with the actual configuration (with 9 ky003 modules plus mentioned above components) and the other one is the one focused to be on the PCB (since i’m using female connectors for data IN and also female connectors for the common ground and 5v+ from arduino). I designed first the BB view with my components and after that, I started designing my PCB. The thing is that I have to power supply some 2812b led strips, and several components on my PCB with those 5v.įor connections, I choosed screw terminals to PCB (up to 6A each), but I decided to take differents inputs from the PSU to the PCB just to avoid the traces to get burn.Īll traces has commond GND with Arduino Nano, but a separated live (+). Please also attach any files that help explaining this problem

My version of Fritzing and my operating system:Ġ.9.3b (I understand that this is a beta version, but this is a pretty bad problem, so I thought I should report it.) What I expected should have happened instead:Įach uniquely named net label should be a unique net, with no cross-connections between labels of different names. So I deleted those and created new ones and that fixed that issue, but fixing that one caused several others to become cross connected.

That seemed to fix the issues, till I found another one that was cross-connected. I deleted the faulty net labels and created new ones. Everything seemed ok at first, then I began to notice that several nets with different names were being treated as the same net on the pcb layout. Steps I took that resulted in the problem:Īttempting to create an Arduino Nano projects - I created net labels for most of the pins, then created matching net labels for several screw terminals and male connection points.
