Microcontroller PCB for Attitude System (Thesis)

Didn't feel like coding yesterday, so I decided to make a uC PCB for the attitude sensor stack. I wanted to make the PCB a little more general purpose than just a PCB for interfacing with the sensors, so I've added pin-rows for all I/O-pins with annotation. Other than that, I've added header for USART, two I2C headers, a voltage regulator, and three regulated power headers. As with the other sensor PCBs, I have added 3.5mm mounting holes in the corners so that the cards can be stacked.



I'm trying out yet another PCB fabricator, iTeadStudio, which is by far the cheapest I've seen. For ten 50x50mm two-layered, green solder mask and HASL plated, it cost $14 including shipping! I also added the 'Open PCB' option, which is where they will send you two random PCBs from another order. How cool is that!

I am a little concerned that I've pushed the tolerances a bit, but we'll see when I get the PCBs. ITead specify 6mil a minimum, and recommend 8mil (0.2032 mm), but I think it should be fine.

I'll probably get the boards in a couple of weeks time, until then I will keep program using Atmels STK600 monster of a dev kit. I'll get a ICD debugging header so I don't have to lug it around with me, not to mention that horrible ZIF socket system...
