This tutorial demonstrates how Mongoose Library can be used on an RP2040-based board with the addition of a W5500 chip, using Mongoose's built-in TCP/IP stack.

Features of this implementation include:

- Uses the Raspberry Pi [Pico-SDK](https://github.com/raspberrypi/pico-sdk)

- Uses Mongoose's built-in TCP/IP stack, which includes a W5500 driver

- Does NOT use an external network stack like lwIP, or RTOS like FreeRTOS

- The device keeps a connection to an external MQTT server

- The Web dashboard provides:
  - User Authentication: login protection with multiple permission levels
  - The web UI is optimised for size and for TLS usage
  - Logged users can view/change device settings and communicate to the MQTT server
  - The web UI is fully embedded into the firmware binary, and does not need a filesystem to serve it, making it resilient
