With a different firmware configuration, the MSP430F2618TPM could be replaced with a 2617, 2619, 2417, 2418, or 2419 chip.

Resistor values can be approximated. Be sure to get the 64 pin variant of the MSP430F2618, as 80-pin versions are also manufactured.

Please the components as shown the comments to this Flickr image. As this is a surface-mount design, be sure that you are familiar with such techniques or have assistance before beginning assembly.



Build and flash firmware with the following commands. This board self-flashes over USB through a masked-ROM bootloader, so there is no need for an external programmer.

export board=goodfet42
make clean install
