Help for a newb

autodeskguest

Hello,

 

I am looking to etch my own pcb for a small project I am working on. I plan

on designing the circuit with Eagle. The circuit itself is very simple, but

requires a lot of traces. It will consist of 12 piranha rgb common anode

leds laid out evenly on a 4x3" board, for which each of the r, g and b

channels will be connected to one tlc59116 driver (so one driver per

color). An external connector provides vcc, gnd and i2c comms.

 

Now, I know I could do this with a perfboard and lots of wires.

 

My question is: given the number of traces, does this even sound reasonable

on a one layer pcb (and jumpers on top as needed)? I kind of feel this

really would require more layers, therefore requiring a professionally-made

pcb (which defeats the purpose of diy/hobby/do it for the fun of it)

 

Keep in mind this is for a personal project, for the fun of learning new

things.

 

Any advice appreciated.

    If it is for the fun of learning I would say go ahead and give it a try

    and see if you can fit the traces.

    This is the fun part, like a puzzle where you may or may not have all

    the pieces.
