HC-06 Bluetooth RX & TX voltage (3v3 || 5v) I acquired a HC-06 Bluetooth module, and understand that the voltage on the pins must be 3v3 and therefore requires the use of a voltage divider to lower the Arduino's 5v to 3v3 like this.



But the page where I purchased the product says the following:


  interface level 3.3V, you can directly connect a variety of SCM (51, AVR, PIC, ARM, MSP430, etc.), 5V microcontroller can also be directly  connected, it can not pass without MAX232 MAX232!


Does this mean I can connect without using a voltage divider?

What does "it can not pass without MAX232 MAX232!" mean?
Some chips that run on 3.3v have 5v tolerant inputs. But it doesn't look like the BC417 does (looking at the datasheet). 

So just add the voltage divider.
