He’s using an i2c temperature sensor , and we think the PCA9517 Level-Translating I2C Bus Repeater that makes it possible is a perfect match for the RPi. This is a Texas Instruments part.

Whether or not you need this Raspberry Pi board, this is still an interesting project for anyone working with these interfaces. If you’re interested, we’ve looked at differential I2C in the past.

Practical Applications and Use Cases The Raspberry Pi I2C Multiplexer is particularly useful in scenarios where multiple I2C devices need to be connected to a single Raspberry Pi.

The Raspberry Pi weather station uses a tiny Pico W main board has the main processor and connects to a web server to display data. Weather metrics are collected using a DFRobot Gravity I2C BME280 ...

The Raspberry Pi Foundation is finally designing a microcontroller with its own chip. Here's how you can use it for your projects and everything you need to know about its features and specs.
