[Reference-Robobuilder-Korean] 3.3V and 5V signal written by the MCU writing to communicate with wCK

ROBO Builder kit instead of the default controller, such as ARM or the DSP because you want to use another MCU to be a lot of my other cases, the signal level is a circuit that can be useful for this is when the resistor 3 and diode in one simple to configure can

Based on recent expensive experience it is also a good idea to add a port protection IC on the wCK bus side. This is suitable:
http://www.st.com/internet/com/TECHNICA ... 001361.pdf

The wires on the wCK are not particularly good, and in combination with metal frames and 11.1V LiPo, shorts and cut wires can cause major damage. The protection device will help protect the MCU, though a series 47R resistor on rxd (data out to wCK) will help too. The Protector will also go some way to protect the servos, which otherwise appear to have no protection.

Great pictures :D
