Arduino, and Pi Pico, builds on the Raspberry Pi RP2040
Not only has Raspberry Pi launched its first microcontroller-class product – the RP2040, used by the Raspberry Pi Pico – but then Arduino have built on it with the Arduino Nano RP2040 Connect.
The RP2040 is newly developed at the Raspberry Pi Foundation and the Pi Pico builds on it (see above) as a standalone board option for embedded development or as companion piece to your Raspberry Pi computer, perhaps serving first steps with a microcontroller.
Basically, we are talking about interfacing your Raspberry Pi to the outside “real” world, whether it is reading sensors, connecting to networks or driving actuators.
