 On Melzi one of the unused buffer of soldered IC 4050D takes over the mandatory level-shifting (5V -> 3.3V). Overall only 5 wires have to be soldered. Note that the TXD outputs are connected in parallel which is not recommended. On Arduino boards the serial chip is connected to the main IC via 1kOhm resistors for this reason. This are not present in the Melzi board design. On Melzi one of the unused buffer of soldered IC 4050D takes over the mandatory level-shifting (5V -> 3.3V). Overall only 5 wires have to be soldered.
