Fresh PCB and new design

A project log for Atmega*8 Breadboard Backpack

Instant ICSP/FTDI headers that fit over your Atmega*8 on the breadboard.

I finally received the PCBs from OSH Park and they worked great right out of the gate. I tried round machine pins, instead of the usual break away headers, and found they felt much better when plugging the backpack in. Pictures and more info after the break.

A New Design

I also created a new design that has LEDs for the MOSI and MISO lines. These will show programming status and double as LEDs that can be used for impromptu debugging on PB3 and PB4. I should be getting the new PCBs next week.

Erm, beware, the AVR can drive quite a bit of current, but the programmer might not be able to... I throw my LED on MISO, but not on MOSI for that reason. OTOH, with the uber-brightness of LEDs these days, and a large enough resistor, probably OK.
