In this article we take a look at the newly released Raspberry Pi PIco.
This is not a SBC like a standard Raspberry Pi 4, for example you cannot run an operating system like linux on it. Think of it is an Arduino Nano from a size point of view but way more powerful and an Arduino from a development point of view
You can experiment by adding hardware like lcds, sensors and other modules to it. Lets look at this new board in more detail.
Requirements
You will need a USB cable and some headers, this is truly a barebones development.
You do not need an external SD card as your programs are uploaded to the onboard flash
It can be reprogrammed over USB from a Raspberry Pi or other computer using the C/C++ SDK or the official MicroPython port. At the bottom of this article we have various documentation links.

Summary
This is a low cost board which is designed to fill the low cost maker market, similar to an Arduino. The benefits of this is unlike other development boards there is already good documentation and support
You may need a few extras and the board does not have any wifi or bluetooth capabilities but these can be added with other boards. Maybe future variants can add these capabilities.
At under £4 its well worth a purchase to experiment with
