ATmega & PIC Prototyping PCB

[CaptainObvious]

Hey All,

I have a PCB I use for prototyping DIP PIC projects, and it's worked very well for me. However, I've recently wanted to have one that does the same for ATmega. I've re-worked my prototyping PCB to include SMD PIC and ATmega. The PIC pads can support either 20-pin or 8-pin PICS. The ATMega is the venerable 328P. I've broken nearly all the signals out on the two header rows (all except for the XTAL on the ATmega)...from there, it's just a hay-wire away to wherever you want the signal to go on the prototyping area below. The lower pads are all connected (by row) as the silk-screen indicates. This works well for DIP chips, pull-up/down resistors, extra through-hole components, etc.

Note: You can only have a PIC **OR** and ATmega on here at a time...not both. If you NEED both, you could put a DIP 328 or a DIP PIC on the prototyping area below.

If I get any time, I might tinker with the routing...this is largely auto-routed...I know it could be better...but it's a slippery slop into madness! Plus, we're talking about 64Mhz processors here.

I'd welcome any feedback / ideas.

Well, even less, the ATMEGA operates at 16MHz (or 20MHz with an overclock and firmware update I believe) but alas, I like the protoboard!

One thing I might recommend would be throwing a 0805 LED (or similar) + current limiting resistor for a "power signal" or an "on" light basically! (Mainly for a simple glance to see if the 5V and GND rails are "live")
