Raspberry Pico Adventures

CircuitPython Day 2024 will be next Friday (Agoust 16), so here is a simple project! I am using a few modules I got in my drawers: An RP2040 Feather board. This is a nice RP2040 board with 8 MB of Flash and a battery charger (not used in this project). A BMP390 sensor. I chose this particular board because it has a  STEMMA QT connector, just like the Feather board. A 128x64 pixels OLED display, with I2C interface. A 4 by 4 WS2812 RGB LED matrix. This project aims to use the sensor to measure temperature, air pressure, and altitude, show this information in the OLED display and set the RGB LEDs to a color based on the temperature.

On August 8th, Raspberry announced a new version of the Pi Pico board, the Pi Pico 2, along with a new microcontroller, the RP2350 / RP2354. In this post I will tell the highlights of these new products, along with my comments.
