The RP2040 has a large on-chip memory, symmetric dual-core processor complex, deterministic bus fabric, and rich peripheral set. It’s augmented with a unique Programmable I/O (PIO) subsystem and provides unrivalled power and flexibility. It has the lowest possible barrier to entry for beginner and hobbyist users with detailed documentation, a polished MicroPython port, and a UF2 bootloader in ROM. RP2040 is a stateless device, with support for cached execute-in-place from external QSPI memory. This design decision allows a choice of an appropriate density of non-volatile storage for applications, and to benefit from the low pricing of commodity Flash parts.

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.
