It’s time to explore the new series of microcontrollers based on the rp2040 chip from the Raspberry Pi Foundation. As usual, we are going to use a generic Arduino IDE and C language.
WeAct Studio rp2040: high-resolution pinout and specs
Waveshare rp2040-zero: high-resolution pinout and specs
Raspberry Pi Pico W: high-resolution pinout and specs

For me, It’s very important the network connection and network limitation on STM32F4 It’s very tedious. Adafruit offers a solution, but I think that a shield It’s more usable.

The sensor GY-273 QMC5883L clone HMC5883L magnetometer for Arduino, esp8266, and esp32 is cheap and reasonably precise but needs some check for the clone version.
We have already looked at how to add a wiring connection to an STM32, but sometimes the only solution can be a Wireless or WiFi connection, and in this article we are going to see how to manage a complete WiFi solution.
I love the I2C protocol, and when I need a sensor, every time I try to find one with this protocol, I have also written some libraries for various sensors that use I2C.
In this first article, we are going to learn the basics, then how to create a network with our Arduino UNO and MEGA. Arduino has an interesting feature that can work as a Master and as a Slave.
