The MegaBitty only has TTL level RS-232 on it, so some type of level
shifting is required.
"HVWTech" made a very nice little adapter.
Once feature that I really like about the HVWTech adapter is that by soldering
some 0.1" headers in the 4 pins along the back and the two pins next
to the "HVWTech" on the board, and the two pins in the same spot across
the board, you can then plug it into a solderless breadboard.
