We are going to discover the Raspberry Pi Pico series of prototype boards built using RP2040, the flagship microcontroller chip designed by Raspberry Pi.
We have already talked about the internal flash memories for rp2040 boards and other microcontrollers, which are very useful for storing pages or static files. However, they are not suitable for logging or similar applications, so we will learn how to connect and use an SD card which can have a lot of space, a very small form factor, and low power consumption.
Even though Raspberry Pi Foundation has released the Pico W version, I still find this tutorial useful for adding WiFi to rp2040 boards using an ESP32.
We will use an esp32-wroom-32 (or esp32-s) as WiFi coprocessor and the full potential WiFiNINA library to handle it.
In this article, we are going to explore the w5500 module with our Raspberry Pi Pico, w and the other rp2040 boards. w5500 is a quite powerful device that allows an Ethernet wired connection.
We continue to explore the rp2040 devices, very interesting microcontrollers. All prototype boards come with integrated SPI Flash. Raspberry Pi selected the LittleFS filesystem to manage this storage, a good compromise between functionality and performance.
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.
