BankStick X2 ready to etch, can anyone verify the layout?

Hi, I thought about training myself tu use Eagle app doing a BankStick  for 2 chips, and then some more, like 1, 2, 4, 6 ,8 to cater for anyone needs, easier to etch than stripboarding, at least for me ;D

So, can anyone more experienced than me(almost everyone here I guess)tell me if I got this one right please?

It looks like this design already allows for this, but it would be nice to explicitly make sure 90-degree headers can be used.

The only reason I could come up with for wanting a Bankstick board with less than the maximum amount of memory would be size - so, I’d try to get the board a bit more compact if I were you :smiley:

BTW, there IS an error in the board. Both ICs have all address pins dragged to ground. See http://ucapps.de/mbhp_bankstick.html to fix this. I added a layout I just threw together, toi give you an idea about how to minimize size a bit.

The second picture has the right IC mounted to the other side of the board, reducing size even further :smiley:

These layouts do not have mounting holes in them yet. I merely posted them to give you an idea of what I think you should go for.

Yes, noticed that error too, hard to read that tiny schematic ;D

nice examples there!!! still a lot to learn for me, the good thing is that I’m getting to know the program :slight_smile:

i’ll guess it will be hard to improve on your design, but i’ll come back with some more, thanks!

whatever you do, don’t try to build that second montrosity…

jimp, after our “discussion” about the mini-tiny-pokey board, I actually tested double-sided component stuffing with overlapping ICs. It’s not fun to solder, but it works :smiley:

With machined-pin sockets, you have a bit of access to the topside of the pin, so you can do double-sided boards without too much trouble.
