What is it?

This board, named the Dos Ocho (2-8, get it?) gives the MSP430 breaks out all 28 pins of the MSP430G2553. R28 and R29 (0 ohm resistors to P2.6 and P2.7) will be populated by default. The passives (bypass capacitors and reset line passives) can be added as options.

Silkscreen displays capabilities of each pin, including Port3.

Why did you make it?

I made it because I like MSP430 and wanted to go through an exercise in small scale manufacturing. I also like to use Port3 as a bitbanged debug port (I can push 1 byte through to an FTDI FIFO in just a few clock cycles!).

What makes it special?

The value line LaunchPad board only has 20 pins. This board adds 8 more pins, leveraging the capabilites of Port3 capability. Port3 enables the uses of all 3 outputs of both TimerA0 and TimerA1, allowing for up to 6 timed outputs.
