3.3-5V įtampos keitiklis I2C

If you’ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. This logic level converter is a small device that safely steps down 5V signals to 3.3V and steps up 3.3V to 5V. This level converter also works with 2.8V and 1.8V devices. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side. Two inputs and two outputs are provided for each side.

• Dimensions: 0.5×0.6″
• 2-channel high-voltage and low-voltage logic logic bidirectional translation
• Two channels of high-voltage logic low voltage logic into a one-way conversion
• Breadboard module is compatible, can be directly inserted in breadboard use
• Instructions for use: [high voltage of 5V low voltage of 3.3V for example]
  • HV to the 5V Power
  • LV to 3.3V Power
  • GND to GND, two power supply share GND
  • Input 5v TTL at RXI, then Output 3.3v TTL at  RXO
  • TXI Input or Output 3.3V TTL, TXO input or output 5V TTL, TXI and TXO bidirectional reversable
