There are TWO SETS of power and data lines that are ELECTRICALLY ISOLATED! Each set is on one half of the isolation barrier.
Power Pins:
- VCC - this is the power pin for each side of the isolator. Each side must be powered, provide (separated) 3 to 5 VDC on both sides!
- GND - this is the ground pin for each side of the isolator. Each side must be powered, connect the reference ground on either side.
I2C Logic pins:
- SCL - the I2C clock pin, connect to your I2C clock line on either side. There is a 10K pullup to the side's VCC
- SDA - the I2C data pin, connect to your I2C data line on either side. There is a 10K pullup to the side's VCC
- STEMMA QT - These connectors allow you to connectors to dev boards with STEMMA QT connectors or to other things with various associated accessories
