significantly less RAM, no VideoCore GPU, …) – but it draws less power, and has additional features, like the aforementioned PIO, and analog inputs (ADC). The Pico has less resources compared to the Pi Zero W (e.g. This has advantages, like real-time, but also disadvantages – you need to know more about the hardware you are using, and need to implement a lot of functionality which you would take for granted on a modern operating system (e.g. in C), without an operating system, whereas the Pi Zero W will usually run Linux. The difference between Microcontroller ( Pico) and Single-Board-Computer ( let’s say Pi Zero W) is roughly this: you program the Pico directly (e.g. Raspberry Pi Pico, a 4 $ microcontroller board How is a Raspberry Pi Pico different from a Raspberry Pi Zero W? – I’ll go into it in another article in the future), and Pico is a really nice reference platform the RP2040 is implemented on. Raspberry Pi have designed lots of cool features into the RP2040 (my favorite is PIO – programmable IO, where you can emulate lots of hardware interfaces which require precise timing, etc. The Raspberry Pi Pico is a new microcontroller board from Raspberry Pi, sporting the in-house developed RP2040 microcontroller chip. 11 More Pico blog posts at PiCockpit Introduction: What is Pico, what is MicroPython?
