I havent had an update in awhile, so I figured I'd give a status update. The last few months have been hectic, but Ive managed to cram a lot of time towards my project, and am almost ready to finally get my first legit prototype board off to the fab shop. Ive christened it as the Dragonboard.
Its a multiple-use microcontroller board meant for operating RFID modules and gas sensor modules (of which are in the design phase right now). Its a pretty nifty little device that only has a dimension of 3.25 x 2", with an on-board RTC, a 9-16V DC/AC power supply, a 3-Axis accelerometer, an EMI suppression circuit for USB programming, an XBee, and all supporting hardware for the circuits. It also allows for on-board programming of the XBee.
Once I get it back from the shop, I'll post some updates about programming it, operation and whether or not it passes my tests for operation. Im crossing my fingers that this thing works out like Ive planned. Anyways, thats about all I wanted to say about it for now.
