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.

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 ...

A lightweight I2C MicroPython library for the Bosch BNO055 (WCMCU-055) 9-axis sensor on Raspberry Pi Pico, featuring an interactive zero-dependency calibration suite with magnetic True-North alignment ...

This Python library supports the INA219 voltage, current and power monitor sensor from Texas Instruments on Python 3. The intent of the library is to make it easy to use the quite complex ...
