The first run of my Max3100(Maxim IC) breakout board with a couple of different transceivers connected and a closeup of the populated board. I've found a couple of issues with this board that need to be corrected(this is what happens when you try to rush something).
The errors were correctable but they also require a second run...This should give me something to work with at the moment though and give me some ideas on how to improve on this current design.
Currently this board allows you to connect a UM96(LN?), Xbee explorer board and bluesmirf bluetooth adapter. All of these devices are currently sold by sparkfun.com. This board actually allows you to connect anything that has a rx/tx serial signal to be connected, you just have to make sure you get the correct pins and you are set.
This was designed with the MSP430 launchpad in mind and for procs that have SPI interfaces. Some specs on the chip that were useful: 8 word fifo buffer, interrupt with 4 maskable sources, hw handshake control lines(broken out though not ideally placed) and nice voltage range(2.7-5.5v)
