## Questions & Answers

**Q: Is this compatible with a Raspberry pi?**
A: The simple answer is yes. We use it as an I2c multiplexer to access an array of magnetic sensors which cannot be assigned to different I2c addresses. Since there are two i2c channels on Raspberry Pi 3B's and 4b's, we run two different sensor arrays on a single Pi, or each array being run by its own Pi, depending on how intense the data acquisition volume is required.
