(5) BVCC then 3V system power supply       (6) BSCL connected 3V system SCL

(7) BSDA connected 3V system SDA        (8) BGND then 3V system GND

Applications :
Single Chip Microcomputer and 3.3V Single Chip Microcomputer Serial Communication .
2,3.3V serial port download and 5V microcontroller serial communication .
3,5V microcontroller and 3.3V application module serial communication .
Instructions for use:
Wiring instructions:
LV (1-4) the TTL input and output 3.3V, the HV (1-4) Input the TTL output 5V, the LV (1-4) and the HV (1-4) two-way conversion between

note:
1, if the high pressure area and low pressure area of ​​the power has been a total of this module in the G only need to take one place.
2, the conversion module is equivalent to a straight line, each port are one by one correspondence, but the voltage is not the same as the two sides,
Thus achieving the communication between different levels .
3, the module can not be used as a regulator or transformer function, can only be used for IO port
Level between the small current communication .
4, the module row pin without welding, but there are matching .
