What "board type" will you be using for pinouts? Or will you be making up your own?
I see a lot of unrouted traces.
You have 2 pins you are not bringing out at all? That is a waste. Especially as they are PWM pins.You have 2 pins just driving onboard LEDs? That is a waste. That's 4 IO that you've taken away.
Add a diode from RST/ (anode) to +5 (cathode) to prevent any spikes from looking like the start of a high voltage programming cycle, with results in the chip looking like it's hung.
I haven't seen this done in any of the AVR board reference schematics
Really? Where were you looking?
I say "waste" because PWM pins always seem to be at a premium. If you're after SRAM instead and specific size, I can appreciate that too.
I made one change so that D[0..4] is RXD1, TXD1, SCL, SDA, instead of RXD0, TXD0, RXD1, TXD1 like the Goldilocks has it.
DIP-30 is a standard package, right?
