Hello,
This is my first attempt at designing a AVR programming board for ATMEGA328 and ATTiny84, I am planning on improving it further, possible by adding a slot for ATTiny85 as well.
I am planning on manufacturing this at home using the lazer print method (the top layer on the schematic is a manually wired jumper) but I am unsure as to weather the clearances are suitable. My trace sizes are 0.016 and clearance around pins in 10mil. this is my first time trying home PCB manufacture and I am unsure whether this will be sufficient.
