Let’s start with preparing our Pico for this tutorial.

Quickstart IoT - Raspberry Pi Pico RP2040 with WiFi.

Getting Started with Raspberry Pi Pico and CircuitPython.

The project in this post is a combination of different examples from Adafruit: Most of these examples use a different “flavor” of MicroPython, called CircuitPython, which is based on the same Python implementation, but more focused on beginners, education, and getting started tutorials. An extra advantage of the Adafruit products is the big amount of documentation they provide on their website. Of which the Adafruit AirLift ESP32 WiFi Co-Processor Breakout Board is probably the easiest and cheapest at 9.95$. Luckily there are different possibilities to add WiFi to the Pico,

To achieve this very low price, the Pico doesn’t contain wireless functions. These grounds even have a different shape on the board (no rounded corners), to make it easier to find the correct pin you want to use.įor this post we will extend the Pico with a WiFi module and one distance sensor, as an example how you can easily send sensor data to HiveMQ Cloud from this inexpensive board. The Pico provides a lot of GPIOs which are grouped very nicely by separating them with a ground connection. Programming can be done with a C/C++ and MicroPython SDK. Was available when the board was launched. The Raspberry Pi Foundation made sure a very extensive documentation site But the biggest surprise of this Pico: the price of only 4$! So it’s comparable to an Arduino or similar microcontroller board. This RP2040 features a dual-core Arm Cortex-M0+ processor with 264KB internal RAM and support for up to 16MB of off-chip Flash,Ĭombined with a wide range of GPIOs (supporting I2C, SPI, and Programmable I/O (PIO)). This is a completely new type of board as it’s not a full Linux PC,īut a microcontroller chip (RP2040) developed by Raspberry Pi itself, on a small and versatile board.

In January 2021, the Raspberry Pi Pico was introduced. In the third blog post of this series, I am going to add some more data to the messaging system with another member of the Raspberry Pi family, Raspberry Pi Pico. In the second post of this blog series, we used Java on the Raspberry Pi mini computer to send sensor data to HiveMQ Cloud, and visualize it on a dashboard.
