Product Features:
Comes with 3.3V voltage, with power indicator Power input with anti-reverse protection, and can not provide more than 150mA of current.
To achieve direct serial 5V and 3.3V level communication.
The maximum stable communication baud rate 28800bps.
Can achieve UART, IIC, 1-wire, SPI and other bus signals 3V-5V level of the two-way conversion.
Compatibility:
AVCC 5V system power supply
ASCL 5V system SCL
ASDA connected 5V system SDA
AGND then 5V system GND
BVCC then 3V system power supply
BSCL then 3V system SCL
BSDA connected 3V system SDA
BGND then 3V system GND
Note:
If the high-pressure area and the low-voltage area of the power has been a total of this module G only need to take a ground.
the conversion module is equivalent to a straight line, each port is one to one correspondence, but the voltage side 2 is not the same,
Thus realizing the communication between the different levels.
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.
this module pin-pin no welding, but there are matching.
