We’ve gotten used to the GPIO-available functions of Raspberry Pi computers remaining largely the same over the years, which is why it might have flown a little bit under the radar: the Raspberry Pi 4 ...

While the Raspberry Pi has very good support for an I2C bus, a lot of very cool chips – including the in system programmer for just about every ATtiny and ATmega microcontroller – use an SPI bus.

This project is a hardware-software validation platform built around an MPU6050 IMU connected to a Raspberry Pi 4B over I2C. The goal is to validate a low-level C driver against a Python golden model ...

This is a circuit python library for interfacing with the DFRobot HX711 scale that communicates over i2c. You can see their libraries for integration with arduino ...
