Is there a reason for the Arduino (Uno) having it's expansion connectors not in 100-mil grid?
Until a few days I tought it would even be possible to plug the long-pin version into a breadboard.
I usually rather do PIC stuff and create my own PCB's. But for playing around I used an Arduino. Now I wanted to make my circuit a little more permanent than in a breadboard (just wired with cables). But when trying to align a velo board I noticed that the two pin rows are in a 50 mil grid and that the PORT D pins (pins 0-7) are also 50mil off-spaced to the connector for pins 8-13 (+SDA,SCL)
Is there a reason for the decision to place those connectors off a 100mil grid?
It just robbed me some fun I couldn't just right start into it but first have to order those proto-shields. Altough they are not really expensive, about 4 € at RS components. It's just that an electronics enthusiast has most probably some velo-boards laying around here and there
