The HomeLab-Isol board is suitable for isolation of data interfaces like RS, I2C, 1-wire and SPI.

The module features 4 isolated bidirectional digital lines as well as an isolated power source. The lines are open-drain with 10K pull-up to VCC at the direct side and to +3.3V at the isolated side.

The VCC interface at the isolated side is +3.3V but a shortcut to the +5V pin is safe if +5V is preferred.
