I’ve finished laying out a tiny breakout board for Texas Instruments’ CC430F513x line of wireless microcontrollers. This board, about 1.5 square inches in size, can be populated with the following items:

• QFN48 footprint for CC430F5133/F5135/F5137 microcontroller
• 18-pin header for power input and fully-remappable I/O ports 1 and 2
• Integrated 433MHz balun
• SMA antenna connector
• 26MHz crystal for radio
• 32kHz crystal for use with CC430′s onboard timers
• RGB LED connected to port 3 pins
• 2-wire JTAG / bootloader / serial connection header (5 pins)
• Reset button

That is to say, everything one would need to get a CC430 wireless application up and running. In the coming weeks I’m going to try to get a couple of these up and running and compile an accurate bill of materials; meanwhile, the untested design is freely available and editable using gEDA‘s gschem and PCB. If anyone’s interested in getting in on the pilot production run, feel free to leave a comment…
