so i know this is a massive ask. and i fully expect to be told to go away unpolitely as its a time stealer of a request.
i downloaded ikad in an attempt to design a pcb for manufacture, i spent about an hour in that program pulling hair and getting heavily annoyed. i couldnt even get started to be honest.
is there by chance a kind hearted individual who can assist me in the design of the pcb with gerber files?
its not exacly a complicated circuit, attiny85-SU based. leds, resistors, pull down resistors, smd equivalent of 2n7000s and some 2 pin headers
i just cannot wrap my head around the pcb creation softwares. its just too much for me to actually understand.
by all means tell me to jog on but if theres someone willing to help i will draw up some pictures of whats going through my head
ive attatched a basic paint image of what i was thinking, no connections just the quantities of components and holes and so on hopefully so anyone thinking of helping with this gets the idea of what im blabbering on about.
except where it says 2 rows of leds i actually meant 3, 2 double "stacks" and a single
that all being said, if theres a better logic level mosfet please feel free to recommend as most it would drive is a couple of amps on motor output (absolute max of course)
If you are lucky then maybe someone will offer to do this for free.
If not, please click 'report to moderator' and ask for this to be moved to 'gigs and collaborations' and be willing to pay for someone to do this for you.
For what it's worth it took me a lot longer than 1 hour to get my head around Kicad using the supplied tutorials.
Try googling this: "PCB design and schematic capture" This sounds like it is your first attempt with a PCB, they are not simple. I have been using KiCad for several weeks and got by with it but I am far from being an expert. I have over 40 years experience using and specifying PCBs. I got 3 for 3 that came out correctly. Maybe you can take a course or so on PCB layout. It is not simply placing parts and connecting them, you need to understand your parts and how they interact with each other via PCB traces. There is decoupling, bulk capacitance, radiation, etc to control.
Good Luck & Have Fun!

please dont take this the wrong way but if ever there was a post to scare someone off having a go at this, that would be it haha. what i mean is it may scare a newbie away from giving it a go
i will draw up a schematic later on once i have found a suitable logic level mosfet instead of those 2n7000s
if i get a schematic done up in kicad and post the file perhaps someone can take a look and make any adjustments needed as im getting some progress done with it but its hard finding the right components in the list, such as surface mount resistors and the IRL540 or surface mount equivalent
is that a suitable upgrade to the 2n7000s? it would be switched by an attiny85 and only run small dc motors, servos or leds, not needing a constant drain of more than 2 amps. all running at 5v including source and drain.
okay so i've got this far, ive used a different mosfet than the IRL540su because the that particular one isnt in the library as far as i can see, im not sure if the mosfets need a pull down resistor between the pin and the gate but added resistors from chip pin to ground as recommended.
the mounting holes at the bottom are power in and power outputs, the ones at the top are for a motor and leds with thier respective resistors in line, as the IRL540 is a N channel the drain all runs off the gnd line.
when i try to load this over to the pcb editor i get a load of "annotation" errors, dont know what these are or how to resolve.
im also not sure those are surface mount resistors used in the schematic as couldnt see one in the kicad library that was clearly marked as surface mount.
the idea is to use as many smd components and get the form factor as small as possible. perhaps someone is able to modify/improve on this? ive added a zip archive with the kicad files in as well as an image of it so far
its also taken 2 hours to get this far so please be gentle haha
that said, at least i am trying just need guidence.

Very unlikley you would make much headway in only one hour to be honest.
I was a regular Eagle user of some 6 years when I first tackled Kicad, it took way way longer than 'one hour' before I had a viable PCB design in Kicad.
Not sure why you expect PCB design to be so easy and quick.
Give it a couple of days, and if you still need help ........................
I'm, by far, not an expert on PCB/circuit design. I'm just a beginner hobbyist.
I've downloaded and tried to use several PCB design programs (including Kicad). They all have different learning curves and support levels.
For me, Eagle has been easier to figure out. Mainly due to the wealth of information available from their website and others. Along with all the videos on YouTube (I learn faster by seeing something done vs reading how to do it).
Not saying Kicad doesn't have the same level of support. Maybe I just stumbled upon the information I needed easier with Eagle?
And I agree with everyone else. 1 hour isn't going to get you very far.

So from that comment, do we assume that you have not tested or breadboarded your intended 'design' ?
I my experience its a waste of time designing a PCB if your not even sure the circuit will work as intended.
