The I2C (Inter-Integrated Circuit) bus is a synchronous serial communication protocol that allows multiple electronic components (sensors, displays, memories, etc.) to be connected within the same ...

A lot of great ICs use I2C to communicate, but debugging a non-working I2C setup can be opaque, especially if you’re just getting started with the protocol/bus. An I2C bus scanner can be a helpful ...

The Challenger RP2040 WiFi is a microcontroller board from iLabs. It combines a Raspberry Pi RP2040 microcontroller with an ESP8285 for Wi-Fi connectivity. The board has two LEDs, one of which is a ...

If you’ve ever been laying out a network I2C devices inside a project box or throughout your robot’s body, you’ll probably know that I2C is not without its pitfalls. But for many of those pitfalls, ...
