What Is the Raspberry Pi Pico / Pico W : The Raspberry Pi Pico is a low-cost, high-performance micro-controller board supporting a number of popular digital interfaces. The Raspberry Pi Pico is built around the RP2040 micro-controller chip designed by Raspberry Pi Foundation in the United Kingdom.
The RP2040 which is the brain of the Pico, is a dual-core Arm Cortex M0+ processor with a flexible clock running up to 133 MHz. The Raspberry Pi Pico W on the other hand is a wireless-enabled version of the RP2040-based board, adding 2.4GHz 802.11n WiFi connectivity. At the heart of the Pico W is the same RP2040 chip used in the original Raspberry Pi Pico, featuring two ARM Cortex-M0+ cores clocked at 133MHz with 256KB RAM; 30 GPIO pins; paired with 2MB of onboard QSPI Flash memory for code and data storage including a broad range of interfacing options.

Getting Started with the Pi Pico – The Raspberry Pi Foundation has been bringing to market some very powerful maker boards supported by good documentation, large ecosystem of vendors and a supportive community that is just unbeatable. I would like to think that the Raspberry Pi Foundation will continue to deliver in all of those areas when it comes to the Pi Pico.
The Raspberry Pi Pico can be programmed in both MicroPython and C/C++ which is absolutely fantastic. While i appreciate the power of C/C++, i just love working with Python and am a huge advocate of Python. MicroPython on the Pi Pico makes it super easy to get started with physical computing and there are tons of reasons you should be giving it a go.
There are tons of tutorials available out there on the internet to get you started and while that can be a boon it can also be a huge challenge, especially if you are just starting out. If you’ve never programmed with MicroPython before and have never played around with a micro-controller before we would recommend picking up one of the basic starter kits which comes with a bunch of LED’s, sensors, breadboards, etc. and most importantly with documentation to help you get started with your learning journey.
Here’s a few links to Raspberry Pi Pico kits which could get you going with your learning journey. Please note that we are not affiliated to any of these vendors, kit manufacturers and you should do your own homework before you invest in any of these kits.
Here are a couple of additional links to kits which you might find helpful.
If you live in Australia, intend to just dip your feet into the world of physical computing with Pico / Micropython and don’t know if an electronics kit is the way to go then here’s some links to get you started. Please do note, it’s always cheaper to get started with an electronics kit however an electronics kit in most cases won’t give you enough of the basic hardware you would need to build more complex projects which you will want to do once you progress with your learning, have moved beyond blinking an LED, playing around with some of the sensors, etc.
The following links will get you some basic hardware you need to get working on the Pi Pico.
