 +Once again, you can get your MSP430 from the nice folks at TI:   [[http://focus.ti.com/docs/prod/folders/print/msp430f2274.html#MSP430F2274IDAR|MSP430F2274IDAR]] or [[http://focus.ti.com/docs/prod/folders/print/msp430f2274.html#MSP430F2274TDAR|MSP430F2274TDAR]].  This is the TSSOP 38 package, and you can get 2 free units of each.

 +  * 2 x 0.1uF 0603 capacitors
 +  * 1 x 330 Ohm 0603 resistor
 +  * 1 x 300 Ohm 0603 resistor
 +  * 3 x RED LED 0603
 +
 +
 +Rest of the parts, except the header, are shared with the [[GoodFET31L]]
 +
 +**Assembly Notes**
 +
 +Should take about 30 minutes to assemble.
 +
 +
 +If you're using [[http://parts.digikey.com/1/parts/682431-led-super-red-clear-0603-smd-ltst-c190krkt.html|this LED]], and using the arrows on the board, I believe the "large U" should be on the same side as the arrow head. The cathode (negative) is the T shaped pad.
 +
 +
 +FT232, resistors, LED's and capacitors added
 +
 +[[Image:Goodfet.jpg]]
 +
 +
 +  *  Add FT232, tag corners or hot plate, check orientation.
 +  *  Add 0.1uF capacitors, can go around either way.
 +  *  Add 300 and 330Ohm resistors, can go around either way.
 +  *  Add 3 LEDs, check orientation.
 +
 +
 +Plug into a USB hub, Two LED's closest to the USB port should flash momentarily. If this works, plug it into a PC and the LED's should flash a couple of times more, and the PC should install drivers.
 +
 +If it doesn't flash, check orientation of the LEDs, if the USB doesn't install, check the chip for shorts or badly soldered pins.
