PCA9306 Voltage Level Converter Module Board

Das Spannungs- Level Konverter Modul hier in der aktuellen Version 2, basiert auf dem PCA9306 IC. Das PCA9306 Board ist ein dualer, bidirektionaler Spannungs- Level- Konverter. Im Vergleich zu typischen / Statischen Level Konvertern erlaubt das PCA9306 Modul eine Levelangleichung mittels I2C Schnittstelle.

Das PCA9306 I2C Modul erlaubt dabei Spannungen

  •  von 1,0V bis 3,6V (Low Side)

und

  • von 1,8V bis 5.5V (High Side)

Diesbezüglich ist das PCA9306 I2C Level Modul in Kombination mit MCU’s wie beispielsweise

  • ESP8266
  • ESP32
  • ESP8285
  • ARM
  • STM
  • STC
  • Arduino
  • Raspberry
  • usw.

einsetzbar.

Die Anbindung des PCA9306 ist dabei denkbar einfach

  •  Low Level Side
    VCC → 3,3V
    SCL → SCL1
    SDA → SDA1
    GND → GND
  • High Level Side
    VCC → VCC
    SCL → SCL2
    SDA → SDA2

 

The Converter Module is based on PCA9306, actual Version 2. The PCA9306 is a bidirectional Voltage- Level- Converter IC. Compared to typical / static Level Converters the PCA9306 supports I2C interface.

THe PCA9306 I2C Module supports 2 Voltage Levels:

  • from 1.0V to 3.6V (Low Side)
  • from 1.8V to 5.5V (High Side)

 

The PCA9306 is perfect Voltage- Level conversion in Combination with a wide range of MCU’s, for example

  • ESP8266
  • ESP32
  • ESP8285
  • ARM
  • STM
  • STC
  • Arduino
  • Raspberry
  • and much more

 

 The PCA9306 connections:

  •  Low Level Side
    VCC → 3,3V
    SCL → SCL1
    SDA → SDA1
    GND → GND
  • High Level Side
    VCC → VCC
    SCL → SCL2
    SDA → SDA2

 

PCA9306 Level Converter Module Features:

  • 2-bit bidirectional translator for SDA and SCL lines in mixed-mode I2C-bus applications
  • Standard-mode, Fast-mode, and Fast-mode Plus I2C-bus and SMBus compatible
  • Less than 1.5 ns maximum propagation delay to accommodate Standard-mode and Fast-mode I2C-bus devices and multiple masters
  • Allows voltage level translation between:


    1.0 V Low Side and 1.8 V, 2.5 V, 3.3 V or 5 V High Side

    1.2 V Low Side and 1.8 V, 2.5 V, 3.3 V or 5 V High Side

    1.8 V Low Side and 3.3 V or 5 V High Side

    2.5 V Low Side and 5 V High Side

    3.3 V Low Side and 5 V High Side

  • Provides bidirectional voltage translation with no direction pin
  • Low 3.5Ω ON-state connection between input and output ports provides less signal distortion
  • Open-drain I2C-bus I/O ports (SCL1, SDA1, SCL2 and SDA2)
  • 5 V tolerant I2C-bus I/O ports to support mixed-mode signal operation
  • High-impedance SCL1, SDA1, SCL2 and SDA2 pins for EN = LOW
